In the title compound, [Ni(C(6)H(3)ClNO(2))(2)(H(2)O)(4)]·4H(2)O, the Ni(II) ion is located on an inversion centre and is octa-hedrally coordinated by four O atoms from four water mol-ecules in the equatorial plane and two O atoms of two 6-chloro-3-carboxyl-ate ligands in axial positions. There are also four lattice water molecules present. The organic(More)
In the title compound, [Co(C(6)H(3)ClNO(2))(2)(H(2)O)(4)]·4H(2)O, the Co(II) cation is located on an inversion center and is coordinated by four water mol-ecules and two 6-chloro-pyridine-3-carboxyl-ate anions in a slightly distorted octa-hedral geometry. In the crystal, complex mol-ecules and lattice water mol-ecules are linked by O-H⋯O and O-H⋯N hydrogen(More)
In the title compound, {[Cu(C(11)H(5)NO(4))(H(2)O)(2)]·H(2)O}(n), the Cu(II) ion is five-coordinated by two O atoms and one N atom of two symmetry-related quinoline-2,3-dicarboxyl-ate ligands, and two water mol-ecules. The water mol-ecules occupy basal and apical positions of the square-pyramidal coordination polyhedron. Each quinoline-2,3-dicarboxyl-ate(More)
