A new tridentate benzimidazole derivative, 2,6-bis (benzo[1,2-d:4,5-d′]diimidazole-2′-yl)-pyridine (Bzdiimpy), was prepared from o-phenylenediamine in five steps with improved methods according to the literature in good yield. The crystal structure was determined by X-ray diffraction analysis. It crystallized in monoclinic, space group P21/c, with a=1.170 8(4) nm, b=2.479 6(9) nm, c=1.215 9(4) nm, a=114.641(7)mpared with the reported analogue 2,6-bis (benz[1,2-d:4,5-d′]imidazole-2′-yl)-pyridine (Bzp).
