RESUMO
In the title compound, [Cu(C(8)H(7)O(2))(C(12)H(8)N(2))(2)](C(8)H(7)O(2))·6H(2)O, the Cu atom is in a distorted square-pyramidal coordination environment. The six crystallographically independent uncoordinated water mol-ecules are inter-connected by hydrogen bonds, completing dodeca-water (H(2)O)(12) clusters which are hydrogen bonded to the carboxyl-ate groups of phenyl-acetate anions, building up one-dimensional anionic chains propagating along [100]. Between the cationic and anionic chains are hydrogen bonds from water mol-ecules to the carboxyl-ate O atoms belonging to the phenyl-acetato ligands.
RESUMO
In the title compound, [Cu(C(4)H(2)BrO(4))(2)(C(6)H(6)N(4))(2)], the central Cu(II) atom lies on an inversion center and is six-coordinated in an octahedral geometry by four N atoms from two chelating biimidazole mol-ecules in the equatorial plane and two O atoms from two 2-bromo-fumarate ligands in the axial positions. O-Hâ¯O, N-Hâ¯O and C-Hâ¯O hydrogen bonds lead to a three-dimensional network.
