A new complex [Zn(bbb)Cl-2].DMF, where bbb is 2-(2-(1H-benzo[d]imidazol-2-yl)benzyl)-1H-benzo[d]imidazole, was synthesized and characterized by element analysis, H-1 NMR and X-ray single crystal structure analyses. For complex: crystal system, triclinic, space group, P-1, a = 9.4661(13), b = 10.3534(14), c = 13.0025(18) angstrom, alpha = 73.477(2), beta = 80.743(2), gamma = 88.658(2)degrees, V= 1205.5(3) angstrom(3), Z= 2. In this complex, the Zn2+ distorted tetrahedron geometry is coordinated by two nitrogen atoms from 2(2-(1H-benzo[d]imidazol-2-yl)benzyl)-1H-benzo[d]imidazole and two Cl-. The complex emits yellow green luminescence with the maximal emission peak at 550 nm in DMF solution. The complex exhibits inhibition on the growth of Eca 109 cancer cell with IC50 value of 8.9 +/- 1.1 mu M, which was lower than that of cisplatin (14.3 +/- 1.4 mu M). This complex has potential application in treatment of esophageal cancer. (C) 2014 Elsevier B.V. All rights reserved.
