Synthesis and structural elucidation of heterobimetallic complexes comprising palladium(II) and a group fourteen element

Synthesis and structural elucidation of some new heterobimetallic complexes of the type [Pd(C2H6N2)(2)M-2(R)(4)]Cl-2 and [Pd(C3H8N2)(2)M-2(R)(4)]Cl-2 are described. These chelates were prepared by treating monometallic derivatives, viz., [Pd(C2H6N2)(2)Cl-2 and [Pd(C3H10N2)]Cl-2 with Group 14 organometallic chlorides, Ph2MCl2, Me2MCl2 or (Cp2MCl2)-Cl-1 (M=Si or Sn and M-1=Ti or Zr). The complexes were characterized by elemental analysis, molecular weight determina-tions and magnetic measurements. Based on infrared, H-1 NMR and electronic spectral studies a square-planar geometry around palladium(II) has been proposed for all the derivatives. Conductivity measurements indicate the ionic nature of all the complexes.
