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.
在标题化合物[Mn(C₂O₄)(C₁₀H₇N₃S)]ₙ中，Mn(II)阳离子被一个2-(1,3-噻唑-4-基)-1H-苯并咪唑配体和两个草酸根阴离子螯合，形成扭曲的N₂O₄八面体几何构型。两个独立的草酸根阴离子位于各自的反演中心上，并将Mn(II)阳离子桥连形成沿[101]方向延伸的聚合物链。噻唑环与苯并咪唑环系统大致共面[二面角 = 4.19 (9)°]。在晶体中，经典的N-H⋯O氢键和弱的C-H⋯O氢键将聚合物链连接成三维超分子结构。
