catena-Poly[[(2-amino-1,3-benzothia-zole-6-carboxyl-ato-κ(2)O,O')(2,2'-bipyridyl-κ(2)N,N')cadmium]-μ-2-amino-1,3-benzothia-zole-6-carboxyl-ato-κ(3)N(1):O,O'].

In the title coordination polymer, [Cd(C(8)H(5)N(2)O(2)S)(2)(C(10)H(8)N(2))](n), the Cd(II) ion is coordinated by a bidentate 2,2-bipyridyl ligand, two O,O'-chelating 2-amino-1,3-benzothia-zole-6-carboxyl-ate (ABTC) ligands and one N-bonded ABTC ligand. The resulting CdN(3)O(4) coordination polyhedron approximates to a very distorted penta-gonal 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 inter-actions [centroid-centroid separations = 3.641 (2) and 3.682 (3) Å].
