The binuclear complexes of NNNN’’ tetrakis (2-methylbenzimidazolyl) p-phenylenediamine (L) with Zn (II) and Cd (II) having composition M2LX4(M=ZnII andCdII, X=Cl ??, NCS ??and CH3COO ??) have been prepared and characterized from the studies of elemental analysis, electrical conductance measurement, magnetic susceptibil-ity, UV and IR spectral analysis. The electrical conductance value of complexes in DMF shows negligible electrical conductance value at 30ºC (~ 10-12 Ohm-1mol-1cm2) 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 stoichiometricand spectral data supported trigonal bipyramidal geometry of these binuclear complexes.
