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


ABSTRACT: 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).
