چکیده
In the title compound, {[Ni(C(10)H(8)N(2))(H(2)O)(4)](C(12)H(8)O(4))}(n), the Ni(II), 4,4'-bipyridyl (bipy) and 3,3'-(p-phenyl-ene)diacrylate (L(2-)) moieties are situated on inversion centres. The bipy ligands bridge Ni(II) ions into positively charged polymeric chains along [101]. The Ni(II) atom is coordinated by two N atoms from two bipy ligands and four water mol-ecules in a distorted octa-hedral geometry. L(2-) anions inter-act with the polymeric chains via O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

In the crystal of the title polymeric complex, [Ni(2)(C(18)H(4)O(10))(C(10)H(8)N(2))(H(2)O)(8)](n), each Ni(II) cation is coord-in-ated by four water mol-ecules in the equatorial plane, and is further bridged by an 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carb-oxy-l-ate anion and a 4,4'-bipyridine ligand in the axial directions, forming a distorted octa-hedral geometry. The 9,10-dioxo-9...

In the title complex, [Pb(C(8)H(7)O(2))(2)(C(10)H(8)N(2))](n), the Pb(II) atom is located on a twofold rotation axis and is six-coordinated by four carboxyl-ate O atoms from two 3-methyl-benzoate ligands and two N atoms from two 4,4'-bipyridine (4,4'-bpy) ligands, displaying a hemi-directed coordination. The 4,4'-bpy ligand has an inversion center at the mid-point of the central C-C bond. The P...

The 4,4'-bipyridine spacer in the title compound, [Co(C(10)H(8)NO(2))(2)(C(10)H(8)N(2))(H(2)O)(2)]·4H(2)O, links the diaqua-cobalt(II) dicarboxyl-ate units into a linear chain; the metal atom lies on a center of inversion in an octa-hedral environment. The coordinated and uncoordinated water mol-ecules inter-act through O-H⋯O hydrogen bonds to form a three-dimensional network.
