The 1:2:1 reaction of CdCl2 . 2.5H(2)O with 3,4-dihydroxybenzoic acid
(3,4-H(3)dhb) and KOH in (PrOH)-O-n-H2O gave the unique, seven-coordin
ate cadmium(II) complex [Cd(3,4-H(2)dhb)(2)(H2O)(3)]. HCl .(3,4-H(3)dh
b). 2.5H(2)O as one of the products. Crystal structure and Cd-13 NMR s
tudies showed that 3.4-H(2)dhb(-) behaves as a bidentate chelate with
ligated atoms being the carboxylate oxygens, but that seven-coordinati
on is not retained in aqueous solution. Copyright (C) 1997 Elsevier Sc
