Abstract
The title compound, [Co3Na2(C72ClNO4)4(H2O)12][Co(C7H2ClNO4(H2O)3]2·6H2O, consists of a centrosymmetric dimer of [CoII(dipicCl)2]2- complex dianions [dipicCl is 4-chloropyridine-2,6-dicarboxylate] bridged by an [Na2CoII(H2O)12]4+ tetracationic cluster, two independent [Co(dipicCl)(H2O)3] complexes, and six water molecules of crystallization. The metals are all six-coordinate with distorted octahedral geometries. The [CoII(dipicCl)(H2O)3] complexes are neutral, with one tridentate ligand and three water molecules. The [CoII(dipicCl)2]2- complexes each have two tridentate ligands. The [Na2CoII(H2O)12]4+ cluster has a central CoII ion which is coordinated to six water molecules and lies on a crystallographic inversion center. Four of the water molecules bridge to two sodium ions, each of which have three other water molecules coordinated along with an O atom from the [CoII(dipicCl)2]2- complex. In the crystal structure, the various units are linked by O-H···O hydrogen bonds, forming a three-dimensional network. Two water molecules are disordered equally over two positions.
