Treatment of 1,1′‐(1,4‐butylene)bis‐1 H ‐benzimidazole) (bbbi) with CoSO 4 ·7H 2 O afforded a novel metal‐organic polymer [Co(bbbi) 1.5 (SO 4 )] n ( 1 ), where the central Co(II) ions are bridged by bbbi ligands, leading to a two‐dimensional layer with reversed triangular‐prism shaped units. Each reversed triangular‐prism shaped unit is made up of six bbbi ligands and six cobalt atoms. Thermal analysis revealed that polymer 1 was stable below 147 °C, and oxidized and decomposed to Co 2 O 3 at about 787 °C, and to CoO at about 914 °C.
