catena-Poly[[[2-(1,3-thia-zol-4-yl)-1H-benzimidazole]-manganese(II)]-μ-oxalato].

In the title compound, [Mn(C2O4)(C10H7N3S)] n , the Mn(II) cation is chelated by one 2-(1,3-thia-zol-4-yl)-1H-benzimidazole ligand and two oxalate anions in a distorted N2O4 octa-hedral geometry. Two independent oxalate anions are located on individual inversion centers and bridge the Mn(II) cations into a polymeric chain running along [101]. The thia-zole ring is approximately coplanar with the benzimidazole ring system [dihedral angle = 4.19†(9)°]. In the crystal, classical N-H⋯O hydrogen bonds and weak C-H⋯O hydrogen bonds link the polymeric chains into a three-dimensional supra-molecular architecture.
