The title complex, [Co(C2H3O2)2(C7H6N2S)2], contains a Co centre with a slightly distorted tetrahedral coordination geometry, involving two acetate ligands and two N atoms from the thiazole moiety [Co-O = 2.0025 (14) and 1.9953 (16) A, and Co-N = 2.0524 (18) and 2.0568 (18) A]. The interplanar angle between the two benzothiazole moieties is 77.86 (3) degrees . The amine groups, acting as donors, participate in intra- and intermolecular N-H...O hydrogen bonds, with N...O distances in the range 2.806 (2)-2.857 (2) A.
