In the structure of the title complex, [Cu(C2O4)(C10H9N3)(H2O)]·H2O, the CuII atom displays a square‐pyramidal geometry, being coordinated by two N atoms from the di‐2‐pyridylamine ligand, two O atoms from the oxalate group and one O atom of a water molecule. The complex molecules are linked to form a three‐dimensional supramolecular array by hydrogen‐bonding interactions between coordinated/uncoordinated water molecules and the uncoordinated oxalate O atoms of neighboring molecules. 相似文献

In the structure of the title compound, [Er(C6H6NO6)(H2O)]n, the Er atoms are eight‐coordinated by one N atom and six O atoms from three symmetry‐related nitrilotriacetate (NTA) ligands, and by one O atom of a water molecule, adopting a distorted square‐antiprismatic geometry. The Er atoms are linked by the NTA ligands into layers, which are interconnected via O—H?O hydrogen bonds between the water molecules and the carboxylate O atoms. The asymmetric unit contains one Er atom, one NTA ligand and one water molecule, all of which are located in general positions. 相似文献

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 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 crystal structure of the title compound, [Mn(C3H2O4)(C10H8N2)(H2O)2], the MnII atom demonstrates a distorted octahedral geometry, being coordinated by two N atoms of a 2,2′‐bipyridine ligand, two O atoms from the carboxylate groups of the chelating malonate dianion and two O atoms of two cis water molecules. The complex molecules are linked to form a three‐dimensional supramolecular array by both hydrogen‐bonding interactions between coordinated water and the carboxylate groups of neighboring molecules and aromatic π–π‐stacking interactions of the bipyridine rings. 相似文献

The title mononuclear complex, [Cu(CO3)(C8H7N5)(H2O)]·2H2O, was obtained by fixation of CO2 by a mixture of copper(II) tetrafluoroborate and the ligand bis(pyrimidin‐2‐yl)amine in ethanol/water. The CuII ion of the complex has a distorted square‐pyramidal environment, with a basal plane formed by two N atoms of the ligand and two chelating O atoms of the carbonate group, while the apical position is occupied by the O atom of the coordinating water molecule. In the solid state, hydrogen‐bonding interactions are dominant, the most unusual being the Watson–Crick‐type coplanar ligand pairing through two N—H?N bonds. Lattice water molecules also participate in hydrogen bonding. 相似文献

Each La3+ ion in the title complex, tetra‐μ‐2‐fluorobenzoato‐κ10O:O′;O:O,O′;O:O′;O,O′:O′‐bis[aqua(4,4′‐bipyridine‐κN)(2‐fluorobenzoato‐κO)lanthanum(II)], [La(C7H4FO2)6(C10H8N2)2(H2O)2], is coordinated by six O atoms from the carboxylate groups of five 2‐fluorobenzoate ligands, one O atom from a water molecule and one N atom from a 4,4′‐bipyridine molecule, thus forming a dimeric molecule. An infinite one‐dimensional dimeric supramolecular chain is formed via intermolecular hydrogen bonds. 相似文献

Reaction of 1,10‐phenanthroline (phen) with iron trichloride in the presence of sodium nitrilotriacetate (NTA) resulted in the formation of red crystals of the title complex, [Fe(C6H6NO6)(C12H8N2)(H2O)]·H2O. The Fe atom has a distorted capped trigonal prismatic coordination comprised of one tetradentate NTA, one bidentate phen molecule and a water molecule. Intermolecular O—H?O hydrogen bonds link the molecules into infinite chains. The chains are crosslinked by hydrogen bonds involving the solvent water molecule, leading to an infinite ladder packing mode. 相似文献

In the title compound, {[Zn(C10H8N2)(H2O)4](C6H5O4S)2·3H2O}n, the Zn atom, the bipyridine ligand and one of water molecules are located on twofold rotation axes. The Zn atom is coordinated by four O atoms from four water molecules and two N atoms from two 4,4′‐bipyridine molecules in a distorted octahedral geometry. The Zn2+ ions are linked by the 4,4′‐bipyridine molecules to form a one‐dimensional straight chain propagating along the c axis. The 4‐hydroxybenzenesulfonate counter‐ions are bridged by the solvent water molecules through hydrogen bonds to generate a two‐dimensional layer featuring large pores. In the crystal packing, the intralayer pores form one‐dimensional channels along the c axis, in which the one‐dimensional [Zn(C10H8N2)(H2O)4]2+ chains are encapsulated. Electrostatic interactions between cations and anions and extensive hydrogen bonds result in a three‐dimensional supramolecular structure. 相似文献

The title compound, [Ni2(C2O4)(C4H13N3)2(H2O)2](PF6)2·‐2H2O, contains a dinuclear oxalato‐bridged nickel(II) complex cation. The structure determination reveals the presence of a centrosymmetric binuclear complex where the oxalate ligand is coordinated in a bis‐bidentate mode to the Ni atoms. The distorted octahedral environment of each Ni atom is completed by the three N atoms of the diethylenetriamine ligand in a fac arrangement and by one O atom from a water molecule. PF6? acts as counter‐anion. A two‐dimensional network of hydrogen bonds links the cations and anions and stabilizes the structure. 相似文献

The title complex, [Mn(C8H4O4)(C10H8N2)(H2O)]n, takes the form of a zigzag chain, with the terephthalate dianion (tp) acting as a tridentate ligand. The MnII center is surrounded by two tp ligands, one water molecule and one 2,2′‐bipyridine (bipy) ligand and exhibits a severely distorted octahedral coordination environment, with cis angles ranging from 57.31 (8) to 123.97 (11)°. The complete solid‐state structure can be described as a three‐dimensional supramolecular framework stabilized by hydrogen‐bonding interactions involving the coordinated water molecule and the carboxy O atoms of the tp ligands, and by π–π stacking interactions involving the bipy rings and the benzene ring of the tp ligand. 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

In the title coordination polymer, [Pb(C5H2N2O4)(H2O)]n, the PbII atom is seven‐coordinated by one N atom and five O atoms from four individual imidazole‐4,5‐dicarboxylate (HIDC2−) groups and one water molecule. It is interesting to note that the HIDC2− group serves as a bridging ligand to link the PbII atoms into a three‐dimensional microporous open‐framework. 相似文献

The two title complexes, [ZnCl2(C11H15N3O3)], (I), and [ZnCl2(C11H15N3O3)]·0.5H2O, (II), are mononuclear zinc(II) compounds. In both structures, the ZnII atom is four‐coordinated in a tetrahedral configuration by one imine N atom and one phenolate O atom of a Schiff base, and by two Cl atoms. The structure of each of the two zinc(II) complex molecules of (II) is similar to that of (I). In (I), the molecules are linked through intermolecular hydrogen bonds, forming a three‐dimensional framework. In (II), the solvent water molecules are linked to the zinc(II) moieties through intermolecular O—H⋯O and O—H⋯Cl hydrogen bonds. The molecules in (II) are further linked via other intermolecular hydrogen bonds, forming a three‐dimensional framework. 相似文献

The asymmetric unit of the title compound, {[Pb(C4O4)(C12H8N2)2(H2O)]·2H2O}n, contains one squarate dianion, two phenanthroline (phen) ligands and one aqua ligand all coordinated to Pb, and two solvent water molecules. The eight‐coordinate Pb metal ion displays a distorted bicapped trigonal–prismatic coordination environment, defined by three squarate O atoms, four N atoms from two chelating phen ligands and one O atom from the coordinated water molecule. The crystal structure contains chains of squarate‐1,2,3‐bridged PbII ions running in the [010] direction. These polymeric chains are linked to one another via offset face‐to‐face π–π interactions between the phen ligands, which lead to a two‐dimensional network extending along the (001) plane. The crystal structure is also stabilized by O—H⋯O intermolecular hydrogen‐bond interactions, forming a three‐dimensional network. 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 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

In the title compound, [In(C8H4O4)(OH)(H2O)]n, the coordination of the InIII ion is composed of six O atoms from three dianionic benzene‐1,2‐dicarboxylate ligands, two hydroxyl groups and one coordinated water molecule in a distorted octahedral geometry. The In3+ ions are linked by the hydroxyl groups to form zigzag In–OH–In chains, which are further bridged by the benzene‐1,2‐dicarboxylic acid ligands to generate a two‐dimensional layered structure featuring three types of rings (six‐, 14‐ and 20‐membered). Hydrogen bonds between the water molecule and a carboxylate O atom, and between the hydroxyl group and a carboxylate O atom, are observed within the layers. In the crystal packing, there are π–π stacking interactions between the benzene rings of adjacent layers, with a centroid‐to‐centroid distance of 3.668 (3) Å and a dihedral angle of 4.8 (2)°. 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
