Bis[4-(2-hy-droxy-benzyl-idene-amino)-benzoato-?O]tetra-kis-(methanol-?O)cadmium.

ABSTRACT: In the title mononuclear complex, [Cd(C(14)H(10)NO(3))(2)(CH(3)OH)(4)], the Cd(2+) cation is situated on an inversion centre. It exhibits a distorted octa-hedral coordination, defined by two carboxyl-ate O atoms from two monodentate anions and by four O atoms from four methanol mol-ecules. The crystal structure comprises intra-molecular O-H?O and O-H?N, and inter-molecular O-H?O hydrogen bonds. The latter help to construct a layered structure extending parallel to (100).

In the title mononuclear complex, [Cd(C(14)H(10)NO(3))(2)(CH(3)OH)(4)], the Cd(2+) cation is situated on an inversion centre. It exhibits a distorted octa-hedral coordination, defined by two carboxyl-ate O atoms from two monodentate anions and by four O atoms from four methanol mol-ecules. The crystal structure comprises intra-molecular O-H⋯O and O-H⋯N, and inter-molecular O-H⋯O hydrogen bonds. The latter help to construct a layered structure extending parallel to (100). ...[more]

Project description:In the title centrosymmetric binuclear Cd(II) compound, [Cd(2)(C(7)H(5)O(3))(4)(C(6)H(6)N(2)O)(2)]·4H(2)O, the six-coordinated Cd(II) atom is chelated by the carboxyl-ate groups of the two 3-hy-droxy-benzoate (HB) anions; the two monomeric units are bridged through the two O atoms of the two carboxyl-ate groups. In the crystal, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π Contacts between the pyridine rings and between the benzene rings [centroid-centroid distances = 3.770 (1), 3.769 (1) and 3.632 (1) Å] may further stabilize the structure.
