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

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

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 title compound, [Er(C5H7O2)3(C12H8N2)], is a mixed‐ligand metal–organic precursor for chemical vapour deposition, with the Er atom being eight‐coordinate. The coordination polyhedron, described as a distorted square antiprism, is formed by three bidentate (chelating) acetylacetonate residues and a phenanthroline ligand in the apical positions. Molecular assembly via C—H⋯O hydrogen bonds generates a sheet structure in the ac plane. Weak co‐operative C—H⋯π interactions form molecular dimers and contribute to the stability of the intersheet packing. The supramolecular assembly contains voids which form hydrophobic porous channels, surrounded by a cluster of dimers. 相似文献

In the monomeric title compound, [Cu(C4H4O5)(C6H6N2O)(H2O)]·1.5H2O, the CuII cation is bound in a square‐pyramidal coordination to a tridentate oxydiacetate (ODA) ligand, a monodentate pyridine‐3‐carboxamide (p3ca) ligand and one aqua ligand, where the two organic ligands form the basal plane and the water O atom occupies the unique apical site. The ODA ligand presents a slight out‐of‐plane puckering in its central ether O atom, while the p3ca ligand is essentially planar. The availability of efficient donors and acceptors for hydrogen bonding results in the formation of strongly linked hydrogen‐bonded bilayers parallel to (101), with an interplanar distance of 3.18 (1) Å and a stacking separation between the bilayers of 3.10 (1) Å, both of them governed by extended π–π interactions. The disordered nature of the solvent water molecules around inversion centres is discussed. The monoaqua compound is compared with the octahedral diaqua analogue, [Cu(C4H4O5)(C6H6N2O)(H2O)2], reported recently [Perec & Baggio (2009). Acta Cryst. C 65 , m296–m298]. 相似文献

In the title compound, [CuCl(C7H7O3S)(C12H8N2)(H2O)], the central Cu atom is coordinated by a water molecule, a chloride ion, an O‐monodentate p‐toluenesulfonate anion and an N,N′‐bidentate 1,10‐phenanthroline ligand. The copper environment is best described as a slightly distorted square pyramid, with bond distances Cu—Cl 2.2282 (9) Å, Cu—OW 1.984 (3) Å, and Cu—N 2.006 (3) and 2.028 (3) Å; the apical Cu—O distance is 2.281 (2) Å. In the supramolecular structure, π–π‐stacking stabilization is observed, and classical and non‐classical hydrogen bonds also play an important role. 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

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 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, [Co(C19H15N3O5S)(C12H8N2)]·5H2O, has a moderately distorted octahedral coordination environment composed of two N atoms of a 1,10‐phenanthroline ligand and one N and three O atoms of an N‐{[4‐(1,3‐benzothiazol‐2‐yl)anilino]carbonylmethyl}iminodiacetate (ZL‐52−) ligand. The ring systems of the phenanthroline and ZL‐52− ligands are coplanar and the complexes pack in layers parallel to the ab plane with the rings of adjacent complexes facing one another. The layers stack along the c axis and are linked by hydrogen bonds involving the five water solvent molecules in the asymmetric unit and O atoms of the acetate groups of the ZL‐52− ligand. This is believed to be the first crystal structure of a complex of a 2‐(4‐aminophenyl)benzothiazole ligand. 相似文献

The title coordination complex, [Ni(C14H14O2PS2)2(C12H8N2)] or [Ni(pMePh‐dtp)2(phen)] (phen is 1,10‐phenanthroline; dtp is diaryldithiophosphate), has a non‐crystallographic twofold axis of symmetry through the Ni atom and the phen moiety. Two O,O‐di‐p‐tolyldithiophosphate (dtp) ions act as bidentate ligands. The central metal atom is coordinated by four S atoms from two dtp groups and two N atoms from the phen ligand. The title compound displays distorted octahedral geometry around the central Ni atom. 相似文献

In the mononuclear title compound, [Cu(C4H4O5)(C6H6N2O)(H2O)2], the CuII centre is bound to a chelating oxydiacetate ligand, a monodentate pyridine‐3‐carboxamide unit and two water molecules, defining an octahedral coordination where the first two ligands form the equatorial plane and the last two occupy the apical sites. The planar oxydiacetate ligand is slightly disordered at its central ether O atom. The availability of efficient donors and acceptors for hydrogen bonding results in a complex interaction scheme where each monomer links to six similar units to define a well connected three‐dimensional structure. A comparison is made with related structures in the literature, and the reasons for their differences are discussed. 相似文献

The crystal structure of the title compound, [Mn(NO3)(C10H8N2)(H2O)3]NO3, contains a monomeric [Mn(NO3)(bpy)(H2O)3]+ cation (bpy is 2,2′‐bipyridine) and a nitrate anion. The MnII ion is coordinated by one chelating bpy [Mn—N 2.241 (3) and 2.259 (3) Å], three water molecules [Mn—O 2.120 (3)–2.188 (3) Å] and a nitrate ligand [Mn—O 2.228 (2) Å] in a distorted octahedral geometry. There are O?H—O hydrogen‐bonding interactions between the ligated water molecules and the ligated and unligated nitrate anions, resulting in double columns of stacked cations and anions. 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

Both structures are composed of very simple monomeric units, which act as the building blocks of complex packing schemes stabilized by a diversity of π–π and hydrogen‐bonding interactions. 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 asymmetric unit of the title compound, [Zn(C10H6NO2)2(C12H8N2)]·1.5C3H7NO, contains one monomeric zinc complex and 1.5 disordered dimethylformamide solvate molecules. The Zn atom is coordinated to one 1,10‐phenanthroline ligand and to two isoquinolinecarboxylate anions (IQC?) via their N and O atoms. The complex exhibits a distorted octahedral geometry around the ZnII atom, with the apical positions occupied by the O atoms of the IQC? ligands. The Zn atom lies 0.049 (1) Å out of the basal plane.

The title complexes, [M(C5O5)(C12H8N2)2], with M = CoII, NiII and CuII, all lie across twofold rotation axes, around which two 1,10‐phenanthroline ligands are arranged in a chiral propeller manner. The CoII and NiII complexes are isostructural, with octahedral coordination geometry, while the local geometry of the CuII complex is severely distorted from octahedral. 相似文献
