Smith, Graham published the artcileStructures of the divalent metal complexes with benzene-1,2-dioxydiacetic acid, COA of Formula: C10H10O6, the publication is Polyhedron (1987), 6(5), 871-9, database is CAplus.
The divalent Ca, Mn, Zn, Co, Mg and Ni complexes of benzene-1,2-dioxydiacetic acid (BDDAH2) were prepared and their structures were determined by x-ray diffraction. [Ca(BDDA)(H2O)2]n.nH2O and [Mn(BDDA)(H2O)2]n.nH2O are isomorphous and isostructural. There is a pentagonal bipyramidal 7-coordination about each metal, involving 4 oxygens of the BDDA ligand, 2 axial waters and a 5th bridging carboxyl O giving a polymer structure. In contrast, [Zn(BDDA)(H2O)3].3.5H2O (and the Co and Mg isomorphs) is discretely monomeric with the bridging position of the Ca/Mn structure replaced by a water. [Ni(BDDAH)2(H2O)4].H2O is monomeric and 6-coordinate, bonded through only 1 carboxyl group of each of 2 trans-related BDDAH ligands.
