In the crystal structure of the title complex, [Zn(C3H2O4)(C12H8N2)(H2O)2], the ZnII atom displays a distorted octahedral geometry, being coordinated by two N atoms from the 1,10‐phenanthroline ligand, two O atoms from different carboxylate groups of the chelating malonate dianion and two O atoms of cis water molecules. The complex molecules are linked to form a three‐dimensional supramolecular array by both hydrogen‐bonding interactions between coordinated water molecules and the uncoordinated carboxylate O atoms of neighboring molecules, and aromatic π–π stacking interactions between neighboring phenanthroline rings. 相似文献

The asymmetric unit of the title compound, {[Ni(C12H6N2O4)(H2O)3]·H2O}n, is composed of a lattice water molecule and a nickel(II) ion that is coordinated by three water molecules and the two N atoms of a 2,2′‐bipyridine‐3,3′‐dicarboxylate ligand. The twist of the 2,2′‐bipyridine‐3,3′‐dicarboxylate unit and the coordination of one carboxylate group to a symmetry‐related NiII atom generate a helical chain that runs along the b axis. Intrahelical hydrogen bonds participate in controlling the orientation of the helices, and both right‐handed and left‐handed helices are connected by interhelical hydrogen bonds into two‐dimensional sheets. 相似文献

In the centrosymmetric title complex, [Mn(C7H8N2O2)4(H2O)2](ClO4)2, the MnII ion is in an octahedral environment, with the equatorial plane being defined by the O atoms of four monodentate carboxylate groups, and the octahedron being completed by two trans‐coordinated water molecules. There are intramolecular hydrogen bonds between the coordinated water molecules and the non‐coordinated O atoms of the carboxylate groups. Hydrogen bonds between the amino groups and the carboxylate groups of neighbouring molecules generate a layered hydrogen‐bonded network. 相似文献

The title compound, [CoII(C10H8O6)(C10H8N2)(H2O)2]n, was obtained by the hydrothermal reaction of CoSO4 with benzene‐1,4‐dioxydiacetate [systematic name: p‐phenylenebis(oxyacetate)] and 4,4′‐bipyridine (4,4′‐bpy). The Co atom lies at an inversion center and the benzene‐1,4‐dioxydiacetate and 4,4′‐bipyridine moieties lie about other inversion centers. The benzene‐1,4‐dioxydiacetate ligands bridge the octahedral CoII coordination centers, forming a one‐dimensional zigzag chain. The chains are further bridged by 4,4′‐bpy ligands, forming a novel two‐dimensional supramolecular architecture. Hydrogen‐bonding interactions between the coordinated water molecules and the carboxylate O atoms lead to the formation of a three‐dimensional network structure. 相似文献

The title one‐dimensional chain nickel(II)–disulfide complex, [Ni(C14H8O4S2)(C5H5N)2(H2O)]n, has each NiII cation coordinated by two N atoms from two pyridine ligands, three carboxylate O atoms from two different dithiodibenzoate ligands and one O atom from a coordinated water molecule, in a distorted octahedral coordination geometry. Each dithiodibenzoate ion links two NiII cations through its carboxylate O atoms, making the structure polymeric. Hydrogen‐bond interactions between two shoulder‐to‐shoulder chains lead to the formation of a ladder‐like structure. 相似文献

The title compound, [La2(C8H3NO6)2(C8H4NO6)2(H2O)6]·2H2O, consists of dimeric units related by an inversion center. The two LaIII atoms are linked by two bridging bidentate carboxylate groups and two monodentate carboxylate groups. Each LaIII atom is nine‐coordinated by six O atoms from five different carboxylate groups and three from water molecules. Hydrogen bonds between the water molecules and between the solvent water and a carboxylate O atom are observed in the structure. In the crystal packing, there are slipped π–π stacking interactions between the parallel benzene rings. Both hydrogen‐bonding and π–π interactions combine to stabilize the three‐dimensional supramolecular network. 相似文献

The title compound, [Zn4(C7H4O3)4(C10H8N2)4]·10H2O, crystallizes as a centrosymmetric tetranuclear cyclic complex containing four ZnII atoms bridged by four carboxylate groups from salicylate ligands, with a syn–anti configuration. Each ZnII atom has a distorted trigonal–bipyramidal coordination geometry, formed by two N atoms of a 2,2′‐bipyridine ligand and three O atoms from two salicylate ligands. The complex is stabilized by intramolecular π–π interactions between pairs of bipyridine rings and a 16‐membered gear‐wheel‐shaped cyclic framework. The hydrogen‐bonding network is formed via the water molecules. 相似文献

The title complex, [Eu(C6H4O2)3(H2O)2], has a double carboxylate‐bridged infinite‐chain structure, with one chelating carboxylate group on each Eu ion centre, which also binds to two water molecules to yield an eight‐coordinate square‐antiprismatic geometry, with Eu—O bond lengths in the range 2.338 (3)–2.594 (3) Å. The pyridine N atoms of the isonicotinate groups do not coordinate to the Eu ions; instead, they direct the formation of EuIII coordination polymers via hydrogen bonding with coordinated water molecules. 相似文献

The reaction of nickel(II) nitrate with terephthalic acid and 2,2′‐bipyridine in dimethylformamide solution gives the title complex, [Ni(C10H8N2)(H2O)4](C8H4O4). The NiII ion is octahedrally coordinated to one 2,2′‐bipyridine and four water molecules and does not coordinate to the terephthalate anion. Hydrogen bonds between the terephthalate anions and the [Ni(2,2′‐bipy)(H2O)4]2+ cations produce a two‐dimensional hydrogen‐bonding architecture with double sheets. 相似文献

In the title compound, [Co(C5H3N2O4)2(H2O)2]·C10H8N2, the Co atom is trans‐coordinated by two pairs of N and O atoms from two monoanionic 4,5‐dicarboxyimidazole ligands, and by two O atoms from two coordinated water molecules, in a distorted octahedral geometry. The 4,4′‐bipyridine solvent molecule is not involved in coordination but is linked by an N—H⋯N hydrogen bond to the neutral [Co(C5H3N2O4)2(H2O)2] molecule. Both molecules are located on inversion centers. The crystal packing is stabilized by N—H⋯N and O—H⋯O hydrogen bonds, which produce a three‐dimensional hydrogen‐bonded network. Offset π–π stacking interactions between the pyridine rings of adjacent 4,4′‐bipyridine molecules were observed, with a face‐to‐face distance of 3.345 (1) Å. 相似文献

The title compound, [Zn(C7H4NO4)2(C12H8N2)(H2O)], has been synthesized. X‐Ray analysis reveals that it is a neutral zinc(II) mononuclear carboxylate complex based on mixed N‐ and O‐donor ligands. The Zn atom is five‐coordinate in a distorted trigonal–bipyramidal coordination environment involving two O atoms of two monodentate 2‐nitrobenzoate molecules, two N atoms of a 1,10‐phenanthroline molecule and one O atom of a water molecule. The axial positions are occupied by a carboxylate O atom from the 2‐nitrobenzoate ligand and an N atom from the 1,10‐phenanthroline ligand [N—Zn—O = 167.66 (9)°]. 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 the title coordination polymer, {[Ba(C8H5Cl2O3)2(H2O)]·H2O}n, each BaII atom is nine‐coordinated by six carboxylate O atoms and one ether O atom from five symmetry‐related 2,4‐dichlorophenoxyacetate ligands, and by two O atoms from water molecules, thus defining a distorted tricapped trigonal prism. The BaII ions are bridged by bidentate water molecules and by tridentate and tetradentate 2,4‐dichlorophenoxyacetate groups, leading to a two‐dimensional layer structure. The crystal structure is further stabilized by hydrogen‐bonding interactions within each layer. 相似文献

The polymeric title complex, {[Mn(C4H4O4)(C10H8N2)(H2O)]·0.5C10H8N2}n, possesses a three‐dimensional open‐framework structure, with the solvate 4,4′‐bipyridine (bipy) molecules, which lie around centers of inversion, clathrated in the channels of the framework. The MnII center is surrounded by three succinate (succ) ligands, one water molecule and two bipy ligands, and displays a slightly distorted octahedral coordination environment, with cis angles ranging from 84.14 (12) to 96.56 (11)°. Each succ dianion coordinates to three MnII atoms, thus acting as a bridging tridentate ligand; in turn, the MnII atoms are bridged by three succ ligands, thus forming a two‐dimensional Mn–succ sheet pillared by the bridging bipy ligands. Two hydrogen‐bonding interactions, involving the water molecules and the carboxy O atoms of the succ ligands, are present in the crystal structure. 相似文献

The title compound, [Cd(C6H4NO2)2(H2O)2]n, forms a one‐dimensional chain structure based on a Cd atom with approximate pentagonal bipyramidal coordination geometry and two nicotinate ligands in different coordination modes. One acts as a tridentate ligand, chelating one Cd atom through the carboxylate group while simultaneously binding to a second symmetry‐related Cd atom through the pyridine N atom; the other acts only as a bidentate ligand through its carboxylate group. Hydrogen bonds utilizing the coordinated water molecules, uncoordinated nitrogen and carboxylate O atoms as acceptors link the chains. 相似文献
