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-coordinate cadmium(II) complex [Cd(3,4-H(2)dhb)(2)(H2O)(3)]. HCl .(3,4-H(3)dhb). 2.5H(2)O as one of the products. Crystal structure and Cd-13 NMR studies showed that 3.4-H(2)dhb(-) behaves as a bidentate chelate with ligated atoms being the carboxylate oxygens, but that seven-coordination is not retained in aqueous solution.
