Abstract: In the centrosymmetric title dimeric Co^II complex, [Co₂(C₇H₃NO₄)₂(C₆H₆N₄OS₂)₂(H₂O)₂].10H₂O, each Co^II 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 Co^II 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-HO, O-HO and O-HN hydrogen bonding helps to stabilize the crystal structure.
