Abstract
The binuclear complexes of NN’NN’’ tetrakis (2-methylbenzimidazolyl) p-phenylenediamine (L) with Zn (II) and Cd (II) having composition M2LX4 (M=ZnII and CdII, X=Cl¯, NCS¯ and CH3COO¯) have been prepared and characterized from the studies of elemental analysis, electrical conductance measurement, magnetic susceptibility, UV and IR spectral analysis. The electrical conductance value of complexes in DMF shows negligible electrical conductance value at 30ºC (~ 10-12 Ohm-1 mol-1 cm2) supported the coordination of anions with metal ions. IR data of thiocyanato complexes suggested N-bonding of NCS group in Zn (II) and through S atom in Cd (II) complexes. The stoichiometric and spectral data supported trigonal bipyramidal geometry of these binuclear complexes.
