In the title compound [systematic name: aqua(1,10‐phenanthroline‐κ2N,N′)(pyridine‐2,6‐dicarboxylato‐κ3O2,N,O6)manganese(II) monohydrate, [Mn(C7H3NO4)(C12H8N2)(H2O)]·H2O, the manganese(II) centre is surrounded by one bidentate phenanthroline ligand [Mn—N = 2.248 (3) and 2.278 (3) Å], one tridentate dipicolinate ligand [Mn—N = 2.179 (3) Å, and Mn—O = 2.237 (2) and 2.266 (2) Å] and one water molecule [Mn—O = 2.117 (3) Å], and it exhibits a strongly distorted octahedral geometry, with trans angles ranging from 144.12 (9) to 158.88 (11)°. Extensive intermolecular hydrogen‐bonding interactions involving coordinated and uncoordinated water molecules and the carboxyl O atoms of the dipicolinate ligand, as well as a stacking interaction involving the phenanthroline rings, are observed in the crystal structure. 相似文献

Crystals of the title compound, [Cr(C4H5NO4)(C6H6N4S2)(H2O)]Cl·H2O, consist of CrIII complex cations, Cl− counter‐ions and lattice water molecules. The complex cation assumes an octahedral coordination geometry, formed by a tridentate iminodiacetate dianion (IDA), a diaminobithiazole (DABT) molecule and a water molecule. The planar DABT group chelates the CrIII ion with normal Cr—N distances [2.0574 (17) and 2.0598 (17) Å], but the DABT molecule is inclined to the coordination plane by a dihedral angle of 17.23 (7)°. In the monodentate carboxylate groups of the IDA ion, the coordinated C—O bonds [1.288 (3) and 1.284 (3) Å] are much longer than the uncoordinated C—O bonds [1.222 (3) and 1.225 (3) Å]. 相似文献

The title compound, {[Mn(C4H4O6)(C12H8N2)]·6H2O}n, has a linear chain structure containing monomeric [Mn(C4H4O6)(C12H8N2)] repeat units. Each manganese ion is six‐coordinate, with the two phenanthroline N atoms [Mn—N = 2.229 (2) and 2.235 (2) Å] and four O atoms from two tartrate anions [Mn—OCOO = 2.1252 (19) and 2.1310 (19) Å, and Mn—OOH = 2.2404 (19) and 2.2424 (19) Å] forming a seriously distorted octahedral coordination environment. Six water molecules exist outside every repeat unit as solvate molecules. Extensive hydrogen‐bonding interactions and π–π stacking of the phenanthroline moieties exist between the chains. 相似文献

In the title compound, [RuII(C10H8N2)3]2[FeIII(CN)6]Cl·8H2O, the [Ru(bpy)3]2+ (bpy is 2,2′‐bipyridine) cations and water molecules afford intriguing microporous honeycomb layers, while the [Fe(CN)6]3− anions and the remainder of the water molecules form anionic sheets based on extensive hydrogen‐bonding networks. The cationic and anionic layers alternate along the c axis. The Fe atom in [Fe(CN)6]3− lies on an inversion centre and the axial cyano ligands are hydrogen bonded to the water molecules encapsulated within the micropores [N⋯O = 2.788 (5) Å], giving an unusual interpenetration between the cationic and anionic layers. On the other hand, the in‐plane cyano ligands are relatively weakly hydrogen bonded to the water molecules [N⋯O = 2.855 (7) and 2.881 (8) Å] within the anionic sheets. 相似文献

The title compound, [Mn(C12H8N2)(H2O)4]SO4·2H2O, was obtained unexpectedly as a by‐product from the reaction of sodium maleate, 1,10‐phenanthroline (phen) and manganese sulfate tetrahydrate. The Mn atom is coordinated by the two N atoms of the phen ligand and four water O atoms in a highly distorted octahedral geometry, with Mn—O distances in the range 2.155 (2)–2.203 (2) Å and Mn—N distances of 2.254 (2) and 2.272 (3) Å. Extensive hydrogen‐bonding interactions involving the water molecules and sulfate anions, and stacking interactions involving the phen rings, are observed in the crystal structure. 相似文献

The title compound, [Hg(C6H4NO2)I(C6H5NO2)], has twofold symmetry along the Hg—I bond. The HgII ion coordinates one I atom [at 2.6045 (4) Å], two N and two O atoms [at 2.298 (3) and 2.481 (2) Å] from one picolinate ion, and one picolinic acid molecule in a very irregular trigonal–bipyramidal coordination. The single hydroxy H atom required for chemical neutrality is both statistically (by crystal symmetry) and structurally disordered, and is involved in an intermolecular O—H⋯O hydrogen bond [O⋯O = 2.455 (4) Å], connecting the molecules into one‐dimensional infinite chains along the [101] direction. 相似文献

The title compound, [HgBr(C7H4NO4)(H2O)], was obtained by the reaction of an aqueous solution of mercury(II) bromide and pyridine‐2,6‐dicarboxylic acid (picolinic acid, dipicH2). The shortest bond distances to Hg are Hg—Br 2.412 (1) Å and Hg—N 2.208 (5) Å; the corresponding N—Hg—Br angle of 169.6 (1)° corresponds to a slightly distorted linear coordination. There are also four longer Hg—O interactions, three from dipicH? [2.425 (4) and 2.599 (4) Å within the asymmetric unit, and 2.837 (4) Å from a symmetry‐related molecule] and one from the bonded water molecule [2.634 (4) Å]. The effective coordination of Hg can thus be described as 2+4. The molecules are connected to form double‐layer chains parallel to the y axis by strong O—H?O hydrogen bonds between carboxylic acid groups of neighbouring molecules, and by weaker hydrogen bonds involving both H atoms of the water molecule and the O atoms of the carboxylic acid groups. 相似文献

In the title chain compound, [Ag(NO3)(C3H7NO)(C26H24P2)]n, the bis(diphenylphosphino)ethane (dppe) components lie across centres of inversion. The dppe units link the Ag+ ions into chains along [100]. A nitrate anion is coordinated to the Ag atom, together with one molecule of N,N‐dimethylformamide (DMF) solvent. At room temperature, the coordinated DMF shows a long Ag—O distance [2.620 (3) Å] and relatively large thermal motion, while at 100 K the Ag—O distance is shorter [2.5588 (19) Å] and the thermal motion is similar to that of the rest of the complex. The behaviour of the DMF molecule is related to the size of the solvent pocket, viz. 146 Å3 at 293 K and 131 Å3 at 100 K. 相似文献

The crystal structure of the title compound, [MnCl(C28H22N2O2)(C2H6O)], has been determined at 173 (2) K in the non‐centrosymmetric space group P212121. The asymmetric unit contains two molecular units. An intermolecular O—H⋯Cl hydrogen bond is formed between the OH group of an ethanol molecule coordinated to the Mn atom and the coordinated Cl− anion, and so polymeric chains of Mn‐containing fragments are formed [O—H⋯Cl = 3.1281 (16) and 3.1282 (15) Å]. The Mn atoms have a pseudo‐octahedral coordination sphere, with the four donor atoms of the Schiff base forming an equatorial plane [Mn—O distances are 1.8740 (13), 1.8717 (13), 1.8749 (13) and 1.8823 (13) Å, and Mn—N distances are 1.9868 (15), 1.9910 (14), 1.9828 (15) and 1.9979 (14) Å]. The axial positions are occupied by an ethanol molecule [Mn—O distances of 2.3069 (15) and 2.3130 (15) Å] and a Cl− ligand [Mn—Cl distances of 2.5732 (6) and 2.5509 (6) Å]. 相似文献

In the title compound, [Mn(C7H3NO4)(C3H4N2)(C12H8N2)(H2O)], the MnII centre is surrounded by one bidentate phenanthroline ligand [Mn—N = 2.383 (3) and 2.421 (3) Å], one tridentate dipicolinate ligand [Mn—N = 2.300 (3) Å, and Mn—O = 2.300 (2) and 2.357 (2) Å], one monodentate imidazole ligand [Mn—N = 2.238 (3) Å] and one water molecule [Mn—O = 2.157 (3) Å]. It displays a distorted pentagonal‐bipyramidal geometry, with neighbouring angles within the equatorial plane ranging from 68.05 (9) to 77.48 (10)°. Intermolecular O—H...O hydrogen bonds link the molecules into infinite chains. The chains are crosslinked by hydrogen bonds involving the carboxyl O atoms of the dipicolinate ligand and the protonated imidazole N atom, leading to an infinite two‐dimensional network sheet packing mode. The complete solid‐state structure can be described as a three‐dimensional supramolecular framework, stabilized by these intermolecular hydrogen‐bonding interactions and π–π stacking interactions involving the phenanthroline rings. 相似文献

Both coordination and hydrogen bonds contribute to networking in the supramolecular title compound, [Co(C6H6NO3S)(C12H8N2)(H2O)3]Cl, which contains a discrete [Co(C6H6NO3S)(C12H8N2)(H2O)3]+ complex cation, formed by one 4‐aminobenzenesulfonate ligand, one 1,10‐phenanthroline ligand and three coordinated water molecules, together with one uncoordinated chloride anion. These discrete cations and chloride anions are connected by hydrogen‐bonding interactions into a two‐dimensional supramolecular motif. Further hydrogen‐bonding interactions consolidate the structural architecture and extend the two‐dimensional supramolecular structure into a three‐dimensional network. 相似文献

The title compound crystallizes as the monohydrate, [Co(SeO3)(NH3)4]NO3·H2O. The crystallographic mirror symmetry coincides with the molecular symmetry; the mirror plane passes through the cation, anion and water molecule. The CoN4O2 octahedron is distorted, with the selenito group acting as a bidentate ligand through two bridging O atoms to the cobalt. The coordinated Se—O distance is 1.742 (2) Å, whereas the uncoordinated Se—O distance is 1.646 (3) Å. A three‐dimensional hydrogen‐bonded network exists between [Co(SeO3)(NH3)4]NO3 and the water molecule. The nitrate anion and water molecule form open pores in the structure when hydrogen bonded to two neighboring [Co(SeO3)(NH3)4]+ cations. Selenium participates in two types of relatively close intermolecular interactions with neighboring charged species (Se?N1 and Se?O3), but does not participate in an interaction with a neighboring O2 atom, the nearest contact distance being 4.638 (3) Å. 相似文献

The title compound, [Mn(C12H8N2)2(H2O)2](C4H4O4S)·[Mn(C4H4O4S)(C12H8N2)2]·13H2O, contains one dianion of thiodiglycolic acid (tdga2−) and two independent manganese(II) moieties, viz. [Mn(phen)2(H2O)2]2+ and [Mn(tdga)(phen)2], where phen is 1,10‐phenanthroline. The MnII atoms are octahedrally coordinated by four N atoms of two bidentate phen ligands [Mn—N = 2.240 (2)–2.3222 (19) Å] and either two water O atoms or two tdga carboxyl O atoms [Mn—O = 2.1214 (17)–2.1512 (17) Å]. The tdga ligand chelates as an O,O′‐bidentate ligand, forming an eight‐membered ring with one Mn atom. The free tdga2− dianion is hydrogen bonded to an [Mn(phen)2(H2O)2]2+ ion, with O⋯O distances of 2.606 (2) and 2.649 (2) Å. The crystal structure is further stabilized by an extensive network of hydrogen bonds involving 13 water molecules. 相似文献

In the title compound, [Mn(C5H3N2O4)2(H2O)2], the MnII atom lies on an inversion centre, is trans‐coordinated by two N,O‐bidentate 1H‐imidazole‐4,5‐dicarboxylate monoanionic ligands [Mn—O = 2.202 (3) Å and Mn—N = 2.201 (4) Å] and two water molecules [Mn—O = 2.197 (4) Å], and exhibits a distorted octahedral geometry, with adjacent cis angles of 76.45 (13), 86.09 (13) and 89.20 (13)°. The complete solid‐state structure can be described as a three‐dimensional supramolecular framework, stabilized by extensive hydrogen‐bonding interactions involving the coordinated water molecules, the carboxy O atoms and the protonated imidazole N atoms of the imidazole‐4,5‐dicarboxylate ligands. 相似文献

In tris(4‐hydroxyphenyl)methane (or 4,4′,4′′‐methanetriyltriphenol), C19H16O3, molecules are connected by O—H⃛O hydrogen bonds [O⃛O = 2.662 (2) and 2.648 (2) Å] into two‐dimensional square networks that are twofold interpenetrated. In tris(4‐hydroxyphenyl)methane–4,4′‐bipyridine (1/1), C19H16O3·C10H8N2, trisphenol molecules form rectangular networks via O—H⃛O [O⃛O = 2.694 (3) Å] and C—H⃛O [C⃛O = 3.384 (3) Å] hydrogen bonds. Bipyridine molecules hydrogen bonded to phenol moieties [O⃛N = 2.622 (3) and 2.764 (3) Å] fill the voids to complete the structure. 相似文献

In polymeric {[Eu(pzdc)(NO3)(phen)(H2O)]·H2O}n [pzdc is 2,3‐pyrazinedicarboxylate (C6H2O4) and phen is 1,10‐phenanthroline (C12H8N2)], each europium(III) ion is coordinated by seven O atoms (from three pzdc anions, a nitrate anion and a water molecule) and the two N atoms of the phen ligand, resulting in a nine‐coordinated europium(III) center with a distorted monocapped square‐antiprismatic coordination polyhedron. Four pzdc anions bridge four europium(III) ions, forming a parallelogram unit, the four vertices of which are occupied by the four pzdc anions. Moreover, each parallelogram unit links six other adjacent parallelogram units, forming a two‐dimensional network with disordered lattice water molecules. 相似文献

The title compound, aquachloro{2,2′‐[1,2‐ethanediylbis(nitrilomethylidyne)]diphenolato‐κ4O,N,N′,O′}manganese(III),[MnCl(C16H14N2O2)(H2O)], is a neutral manganese(III) complex with a pseudo‐octahedral metal centre. The equatorial plane comprises the four donor atoms of the tetradentate Schiff base ligand [Mn—O 1.886 (4) and 1.893 (4) Å, and Mn—N 1.978 (5) and 1.982 (5) Å], with a water molecule [Mn—O 2.383 (4) Å] and a Cl? ligand [Mn—Cl 2.4680 (16) Å] completing the coordination sphere. The distorted geometry is highlighted by the marked displacement of the MnIII ion out of the least‐squares plane of the four Schiff base donor atoms by 0.165 (2) Å. These monomeric MnIII centres are then linked into a polymeric array via hydrogen bonds between the coordinated water molecule and the phenolic O‐atom donors of an adjacent MnIII centre [O—H?O 2.789 (5) and 2.881 (5) Å]. 相似文献

The title complex, [NiCl(C12H16N3O2)2(H2O)]NO3·2CH4O·H2O, was obtained from a methanolic solution of Ni(NO3)2·6H2O, 2‐pyridyl nitronyl nitroxide (2‐NITpy) and (NEt4)2[CoCl4]. The equatorial coordination sites of the octahedral NiII centre are occupied by two chelating radical ligands, with the axial positions occupied by the Cl? and water ligands. The H2O—Ni—Cl axis of the complex lies along a crystallographic twofold axis, so that only half the cation is present in the asymmetric unit. The Ni—Cl bond length [2.3614 (17) Å] is significantly shorter than distances typical of octahedral NiII centres [2.441 (5) Å]. However, with only one nitrate anion per formula unit, the oxidation state of the metal must be assigned as NiII. The 2‐NITpy ligands bend away from the equatorial plane, forming a hydrophobic region around the Cl atoms. Conversely, the ligated water molecule forms moderately strong hydrogen bonds with the disordered methanol solvent molecules, which in turn form interactions with the water of crystallization and the disordered nitrate anion. These interactions combine to give hydrophilic regions throughout the crystal structure. 相似文献

In the title compound, [Li(C5H3N4O2)(H2O)2]n, the coordinate geometry about the Li+ ion is distorted tetrahedral and the Li+ ion is bonded to N and O atoms of adjacent ligand molecules forming an infinite polymeric chain with Li—O and Li—N bond lengths of 1.901 (5) and 2.043 (6) Å, respectively. Tetrahedral coordination at the Li+ ion is completed by two cis water molecules [Li—O 1.985 (6) and 1.946 (6) Å]. The crystal structure is stabilized both by the polymeric structure and by a hydrogen‐bond network involving N—H?O, O—H?O and O—H?N hydrogen bonds. 相似文献
