In the title compound, C(10)H(8)N(2)O(10)·2H(2)O, the skeleton of the dicarboxylic acid mol-ecule is approximately planar, the largest deviation being 0.477 (1) Å for an O atom of a nitro group; this nitro group is twisted out of the plane of the ring by 24.6 (1)°. Adjacent mol-ecules are linked by O-H⋯O hydrogen bonds, which connect the dicarboxylic acid(More)
In centrosymmetric dinuclear title compound, [Cd(2)Cl(4)(C(18)H(16)N(2)O(2))(2)], the Cd(II) atom is seven-coordinated in a penta-gonal-bipyramidal environment defined by two N atoms and two O atoms from one ligand and three Cl(-) anions, two of which are bridging. A π-π inter-action between adjacent pyridine rings [centroid-centroid distance = 3.773 (1) Å](More)
In the title compound, [Cd(NO(3))(2)(C(18)H(16)N(2)O(2))(2)](n), the six-coordinated Cd(II) ion is located on an inversion center and has a distorted octa-hedral environment defined by four N atoms from four 1,4-bis-(pyridin-3-ylmeth-oxy)benzene ligands and two O atoms from two nitrate anions. The ligands link the Cd(II) ions into a ribbon-like structure(More)
In the title compound, (C(20)H(20)N(4))[HgCl(4)], the Hg(II) ion is four-coordinated in a tetra-hedral environment defined by four chloride ions. The dihedral angle between the two phenyl rings is 32.83 (15)°. The protonated 1,1'-[(biphenyl-4,4'-di-yl)bis-(meth-yl-ene)]di-1H-imidazol-3-ium cations, showing a cis conformation, link the [HgCl(4)](2-) anions(More)
In the title compound, [Ni(H(2)O)(6)](C(11)H(7)ClNO(3)S)(2)·2H(2)O, the Ni(II) atom lies on an inversion center and is six-coordinate in an octa-hedral environment of water mol-ecules. The cation and anion are linked through O-H⋯O hydrogen bonding involving the coordinated and uncoordinated water mol-ecules into a three-dimensional network.
In the title compound, {[Co(C(10)H(14)N(4))(2)(H(2)O)(2)]Cl(2)·4H(2)O}(n), the Co(II) atom and the mid-point of the 1,1'-butane-1,4-diyl-diimidazole ligands lie on inversion centers. The Co(II) atom is six-coordinated in a slightly distorted octa-hedral environment by four N atoms from four different ligands and by two O atoms from the water mol-ecules. The(More)
