Abstract

In the title coordination polymer, [Cd(C8H5N2O2S)2(C10H8N2)]n, the CdII ion is coordinated by a bidentate 2,2-bipyridyl ligand, two O,O′-chelating 2-amino-1,3-benzothiazole-6-carboxylate (ABTC) ligands and one N-bonded ABTC ligand. The resulting CdN3O4 coordination polyhedron approximates to a very distorted pentagonal bipramid with one O and one N atom in axial positions. One of the ABTC ligands is bridging to an adjacent metal atom, generating an infinite chain propagating in [100]. A three-dimensional network is constructed from N—H...O and N—H...N hydrogen bonds and aromatic π–π stacking interactions [centroid–centroid separations = 3.641 (2) and 3.682 (3) Å].
