Cadmium complexes stabilized by bis-benzimidazolyl derivatives

Abstract

1863-1867Cadmium halides/perchlorate react with bis-benzimidazolyl ligands (1) 1,3-bis(benzimidazol-2-yl)benzene (L1), 1,3 - bis(l-methylbenzimidazol-2-yl)benzene (L2) and 2,6-bis(l-methylbenzimidazol-2-yl)pyridine (L3) in ethanol to produce complexes of the compositions CdX2Ll.nH2O (X = Cl, n = 1, X = Br or I, n = 2), (CdCl2)2L2, CdX2L (X = Br or I, L = L2; X= Cl, Br or I, L = L3 Cd2(L1)3(ClO4).6H2O and Cd(L)2(ClO4)2.nH2O (L = L2, n = 2; L = L3, n = 0). The complexes have been characterized by elemental analyses, conductance measurements, IR, 1H and 13C NMR spectral studies as well as thermal analysis
