Novel Palladium (II) and Platinum (II) Complex Salts Containing Carbazolium, Indolium and Pyrrolium Cations

A new series of complex salts of the type [RA]2[MCl4] [R=carbazole,indole or pyrrole,A=H or PhCH2;M= Pd(II) or Pt(II)], were prepared and characterized by elemental analysis, molar conductance, IR and UV/Vis spectral studies and magnetic measurements.The results of UV/Vis spectral studies and magnetic measurements showed that the anions complexes have a square planar geometry.
