Bis[2-(2-pyridylmethyl-eneamino)benzene-sulfonato-?N,N',O]zinc(II) dihydrate.

ABSTRACT: In the title complex, [Zn(C(12)H(9)N(2)O(3)S)(2)]·2H(2)O, the Zn(II) ion lies on a crystallographic inversion center and is coordinated by four N atoms and two O atoms from two tridentate 2-(2-pyridylmethyl-eneamino)benzene-sulfonate ligands in a slightly distorted octa-hedral environment. In the crystal structure, the complex forms a two-dimensional network through inter-molecular O-H?O and C-H?O hydrogen bonds.

Bis[2-(2-pyridylmethyl-eneamino)benzene-sulfonato-κN,N',O]cadmium(II) dihydrate.

Project description:The title complex, [Cd(Paba)(2)]·2H(2)O or [Cd(C(12)H(9)N(2)O(3)S)(2)]·2H(2)O, was synthesized by the reaction of the potassium salt of 2-(2-pyridylmethyl-eneamino)benzene-sulfonic acid (PabaK) with CdCl(2)·2.5H(2)O in methanol. The Cd(II) atom lies on a crystallographic twofold axis and is coordinated by four N atoms and two O atoms from two deprotonated tridentate 2-(2-pyridylmethyl-eneamino)benzene-sulfonate ligands in a slightly distorted octa-hedral environment. There are extensive hydrogen bonds of the type O-H⋯O between the uncoordinated water molecules and the sulfonate O atoms, through which the complex forms a layered structure parallel to (001).

Bis[2-(2-pyridylmethyl-eneamino)benzene-sulfonato-?N,N',O]manganese(II) dihydrate.

Project description:The title complex, [Mn(C(12)H(9)N(2)O(3)S)(2)]·2H(2)O, is isotypic with the previously reported Zn(II) and Cd(II) species. The complex was prepared by the reaction of the potassium salt of 2-(2-pyridylmethyl-eneamino)benzene-sulfonic acid with MnCl(2)·6H(2)O in methanol. The complex displays twofold symmetry, with the ligands coordinated in a tridentate meridional-like arrangement through pyridyl N, imine N, and sulfonate O atoms. The metal center has a strongly distorted octa-hedral coordination geometry. The uncoordin-ated water mol-ecules and the complexes participate in a hydrogen-bonding network, forming a two-dimensional structure parallel to the ab plane.
