Bis(μ-pyridine-2,3-dicarboxylato)bis[aqua(2,2′-diamino-4,4′-bi-1,3-thiazole)cobalt(II)] decahydrate

Abstract

In the centrosymmetric title dimeric CoII complex, [Co2(C7H3NO4)2(C6H6N4OS2)2(H2O)2].10H2O, each CoII cation has a distorted octa­hedral coordination geometry formed by a diamino­bithia­zole (DABT) ligand, two pyridine-2,3-dicarboxyl­ate anions and a coordinated water mol­ecule. With its two carboxyl­ate groups, the pyridine-2,3-dicarboxyl­ate anion bridges two CoII ions to form the dimeric complex. Within the chelating DABT ligand, the two thia­zole rings are twisted with respect to each other [dihedral angle = 3.29 (19)°]. Extensive N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonding helps to stabilize the crystal structure.
