چکیده
The asymmetric unit of the polymeric title compound, {[Cu2(C10H2O8)(C3H4N2)4(H2O)2]·C3H7NO} n , contains two independent Cu(II) ions, each coordinated by one water mol-ecule, two imidazole N atoms and two carboxyl-ate O atoms from benzene-1,2,4,5-tetra-carboxyl-ate anions in a distorted square-pyramidal geometry. The benzene-1,2,4,5-tetra-carboxyl-ate anion bridges four Cu(II) ions, forming a polymeric sheet parallel to (010). In the crystal, extensive N-H⋯O and O-H⋯O hydrogen bonds link the polymeric sheets and di-methyl-formamide solvent mol-ecules into a three-dimensional supra-molecular structure.

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

In the title coordination polymer, {[BaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(4)]·2H(2)O}(n), the Ba(2+) cation is deca-coordinate, ligated by four aqua ligands and four [Cu(C(9)H(4)O(5)N)(C(3)H(4)N(2))] 'complex ligands'. The Cu(II)-containing complex-ligands are bridged by the Ba(2+) cations, resulting in a one-dimensional polymeric chain structure. The crystal structure is maintaine...

The title polymeric coordination compound, {[Co2(C10H2O8)(H2O)8]·8H2O} n , was obtained by slow diffusion of a dilute aqueous solution of CoCl2 and the sodium salt of benzene-1,2,4,5-tetracarboxylic acid (H4btec) through an agar-agar gel bridge in a U-shaped tube. The two independent Co(2+) ions are each situated on an inversion centre and are coordinated in a slightly distorted octa-hedral geo...

In the title compound, [Zn(2)(C(10)H(2)O(8))(C(16)H(20)N(4))(H(2)O)(2)](n), the Zn(II) atom is in a distorted tetra-hedral environment, being coordinated by one N atom from a 1,4-bis-(3-pyridyl-meth-yl)piperazine (3-bpmp) ligand, two O atoms from two carboxyl-ate groups of the pyromellitate anion and one water mol-ecule. The distortion of the tetrahedral coordination may be ascribed to the hydr...
