Abstract
Dichloro and dithiocyanto complexes of Pd(II) and Pt(II) with steryl derivatives of 2-alkyl benzimidazole (L) of composition PdLX2 (L = Bzmbl, Bzebl, Bzprbl and Bzpmbt X= Cl– or NCS–) and PtL2X2 (X= Cl– or SCN– and L = Bzmbl, Bzebl, Bzprbl or Bzpmbl) where Bzmbl = 1-(1H-benzimidazol-2-yl)methylbenzylidene, Bzebt = 1-(1H-benzimidazol-2-yl)ethylbenzylidene, Bzprbl = 1-(1H-benzimidazol-2-yl)propylbenzylidene, bzpmbl = 1-(1H-benzimidazol-2-yl)phenyl-1-methylbenzylidene have been synthesized and characterized by electrical conductance, UV and infrared spectral studies. The IR spectral studies of PdLCl2 complexes showed shifting of steryl group ν(CH=CH) vibrations to lower frequencies indicating involvement of HC=CH double bond to Pd(II). The UV and magnetic moment value of Pd(II) and Pt(II) complexes are consistent with square planar structure.
