In the title compound, [Cu(C10H4O8)(C12H8N2)]n, the CuII cation has a four‐coordination environment completed by two N atoms from one 1,10‐phenanthroline (phen) ligand and two O atoms belonging to two dihydrogen benzene‐1,2,4,5‐tetracarboxylate anions (H2TCB2−). There is a twofold axis passing through the CuII cation and the centre of the phen ligand. The [Cu(phen)]2+ moieties are bridged by H2TCB2− anions to form an infinite one‐dimensional coordination polymer with a zigzag chain structure along the c axis. A double‐chain structure is formed by hydrogen bonds between adjacent zigzag chains. Furthermore, there are π–π stacking interactions between the phen ligands, with an average distance of 3.64 Å, resulting in a two‐dimensional network structure. 相似文献

In the title polymeric complex, [Mn(C7H5O3)2(C12H8N2)]n, the MnII atom is located on a twofold axis and displays a distorted octahedral coordination geometry, formed by four salicylate anions and one 1,10‐phenanthroline (phen) molecule. The salicylate anions doubly bridge the MnII atoms to form one‐dimensional polymeric chains. A comparison of Mn—O bond distances with the corresponding Mn—O—C angles suggests a significant electrostatic content in the Mn—O bonds. A face‐to‐face distance of 3.352 (7) Å between neighbouring parallel phen planes indicates π–π stacking interactions between polymeric chains. 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

Both title compounds, [Cd(SO4)(C12H8N2)(H2O)2]n and [Cd(SO4)(C14H12N2)(H2O)2]n, respectively, are polymeric and present the Cd atoms in very similar octahedral environments, provided by the bidentate organic ligand (phenanthroline/dimethylphenanthroline), two aqua molecules and two O atoms from two translationally related sulfate groups, which thus act as links in the resulting polymeric chains. 相似文献

In the polymeric title compound, [Cu(im)Cl(phen)]n, where im is the imidazolate anion (C3H3N2) and phen is 1,10‐phenanthroline (C12H8N2), each CuII ion is five‐coordinated by four basal N atoms (two from two different im anions and two from one phen ligand) and one axial Cl atom, in a distorted square‐pyramidal coordination geometry. Moreover, each im anion bridges two identical {CuCl(phen)}+ cations through its two N atoms, resulting in a one‐dimensional zigzag chain along the crystallographic a axis. In addition, pairs of adjacent chains are staggered by π–π interactions, generating a two‐dimensional layer, and neighbouring layers are further linked by two different kinds of C—H⋯Cl interactions, producing a three‐dimensional network. 相似文献

The copper(II) centre in the mononuclear title complex, [Cu(C7H3NO4)(C14H12N2)]·3H2O, is surrounded by one bidentate 2,9‐dimethyl‐1,10‐phenanthroline (dmphen) ligand and one tridentate pyridine‐2,6‐dicarboxylate ligand, and exhibits a distorted square‐pyramidal geometry. The crystal packing involves both hydrogen‐bonding and π–π interactions. The solvent water molecules link monomers to one another through hydrogen‐bonding interactions, forming ladder‐like chains in the bc plane. Face‐to‐face and slipped π–π interactions also occur between dmphen rings of neighboring molecules and are responsible for interchain packing. 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, [Cd(S2O3)(C16H16N2)(H2O)]n, presents a polymeric one‐dimensional structure running along the P21/c glide direction, with elementary units defined by six‐coordinate CdII atoms bonded to three symmetry‐related thiosulfate groups, a bidentate tetramethylphenanthroline ligand and one aqua ligand. The bridging thiosulfates bind metal centers through two different sequences, viz. Cd—S—Cd′ and Cd′—S′—S′—O′—Cd, defining a closed six‐membered ring. Individual chains are held together viaπ–π interactions to generate two‐dimensional networks parallel to the (100) plane. These, in turn, are connected by much weaker van der Waals interactions. 相似文献

The title mononuclear [Cu(sq)(phen)2]·3H2O complex [sq is squarate (C4O4) and phen is 1,10‐phenanthroline (C12H8N2)] has been synthesized and the structure consists of a neutral mononuclear [Cu(sq)(phen)2] unit and three solvate water molecules. The CuII ion has distorted square‐pyramidal coordination geometry, comprised of one carboxylate O atom from a monodentate squarate ligand and four N atoms from two chelating phen ligands. An extensive three‐dimensional network of OW—H⋯O/OW hydrogen bonds, face‐to‐face π–π interactions between the 1,10‐phenanthroline aromatic rings and a weak π–ring interaction are responsible for crystal stabilization. 相似文献

The polymeric chains run along the c‐axis direction. N—H...O and O—H...O hydrogen bonds involving the coordinating amine groups, nitrate ions and water molecules, as well as cocrystallized noncoordinating nitrate ions and water molecules, generate a three‐dimensional structure. 相似文献

The title compound, {[Ni(C9H4O6)(C14H14N4)]·0.41H2O}n, exhibits a three‐dimensional hydrogen‐bonded supramolecular framework. The NiII cation is six‐coordinated in a distorted triangular prism defined by two N atoms from two 1,3‐bis(imidazol‐l‐ylmethyl)benzene (bix) ligands and four O atoms from two 5‐carboxybenzene‐1,3‐dicarboxylate (HBTC) dianions. The bix molecules and HBTC dianions both act as bidentate ligands, linking the NiII cations to form a one‐dimensional coordination polymer. A two‐dimensional wave‐like net is constructed by O—H...O hydrogen bonds linking adjacent chains. Partially occupied solvent water molecules fill the cavities and link these layers to form a three‐dimensional supramolecular structure via O—H...O hydrogen bonds. The title compound was also characterized by powder X‐ray diffraction and thermogravimetric analysis. 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 structure is a helix with a long pitch of 16.441 (5) Å. A three‐dimensional supramolecular network is further constructed through π–π stacking and hydrogen‐bonding interactions between the helices. 相似文献

In the title PbII coordination polymer, [Pb(C16H10O4)(C14H8N4)(C3H7NO)]n, each PbII atom is eight‐coordinated by two chelating N atoms from one pyrazino[2,3‐f][1,10]phenanthroline (L) ligand, one dimethylformamide (DMF) O atom and five carboxylate O atoms from three different 4,4′‐ethylenedibenzoate (eedb) ligands. The eedb dianions bridge neighbouring PbII centres through four typical Pb—O bonds and one longer Pb—O interaction to form a two‐dimensional structure. The C atoms from the L and eedb ligands form C—H...O hydrogen bonds with the O atoms of eedb and DMF ligands, which further stabilize the structure. The title compound is the first PbII coordination polymer incorporating the L ligand. 相似文献

The copper(II) ion in the syn–anti carboxylate‐bridged one‐dimensional zigzag chain title complex, {[Cu(C16H18N3O2)]ClO4}n, exhibits a distorted trigonal–bipyramidal environment. Two N atoms and one carboxylate O atom of the ligand form the basal plane, while the axial positions are filled by an N atom of the ligand and one O atom belonging to the carboxylate group of an adjacent molecule. The crystal packing is enhanced by C—H⋯O(perchlorate) hydrogen bonds. 相似文献

In the title complex, [Cu(C16H16Cl3N3O2P)Cl(C12H8N2)], the CuII cation presents a square‐pyramidal environment, where the CuO2N2 base is formed by two O atoms from carbonyl and phosphoryl groups, and by two N atoms from a 1,10‐phenanthroline molecule. A coordinated Cl atom occupies the apex. N—H...Cl hydrogen bonds link the molecules into one‐dimensional chains. The trichloromethyl group is rotationally disordered over two positions, with occupancies of 0.747 (7) and 0.253 (7). 相似文献

The solvent effect on the molecular structures of copper(II) complexes produced from the reaction between CuBr2 and 1,10‐phenanthroline is evident. The momomeric title compound, [CuBr2(C12H8N2)(C2H6OS)], which consists of discrete units, is produced from this reaction in dimethyl sulfoxide (DMSO), whereas a polymeric copper(II) compound is known to be produced from the same reaction in the poor coordinating solvent ethanol. The geometry around the copper(II) ion in the title compound is best described as trigonal–bipyramidal distorted square‐based pyramidal, with a τ value of 0.37. The two phenanthroline N atoms, the DMSO O atom and one of the Br atoms occupy the four basal positions, while the second Br atom occupies the axial position. The magnetic susceptibility data also indicate that the title compound is monomeric, but there is still a weak antiferromagnetic interaction between paramagnetic copper(II) centers via the intermolecular `Cu—Br...Br—Cu' contact pathway. 相似文献

In the title compound, {[Zn(C8H4O5)(C12H8N2)]·H2O}n or {[Zn(OH‐BDC)(phen)]·H2O}n (where OH‐H2BDC is 5‐hydroxyisophthalic acid and phen is 1,10‐phenanthroline), the Zn atoms are coordinated by two N atoms from the phen ligands and by four O atoms from hydroxyisophthalate ligands in a highly distorted octahedral geometry, with Zn—O distances in the range 2.042 (4)–2.085 (5) Å and Zn—N distances of 2.133 (5) and 2.137 (5) Å. The {[Zn(OH‐BDC)(phen)]·H2O}n infinite zigzag polymer forms a helical chain of [Zn2(OH‐BDC)2]n units. Face‐to‐face π–π interactions (3.60–3.75 Å) occur between two phen rings belonging to the same helical chain. Consolidation of the packing structure is achieved by O—H⋯O hydrogen‐bonding interactions between the carboxylate O atoms, the hydroxyl group and the water molecule, forming two‐dimensional sheets. 相似文献

The crystal structure of the title compound, [Co(C4H2O4)(C7H6N2)3]n, consists of polymeric chains of the CoII complex. Two maleate dianions and three benzimidazole ligands coordinate to the CoII atom with a distorted octahedral geometry. The maleate dianions bridge neighbouring CoII atoms via both terminal carboxylic acid groups, one of which is monodentate and the other bidentate, to form a helical structure of alternating maleate dianions and CoII atoms, with a pitch height of 9.2667 (17) Å. The absolute structure has been determined, and the crystal contains only right‐handed helices. Intrahelical N—H⋯O hydrogen bonds stabilize the helical structure, while interhelical N—H⋯O hydrogen bonds link neighbouring helices to form the supramolecular structure. 相似文献
