The hetero bimetal ion-pair complexes involving chloro complex anions of Sn(IV)-Cd(II), Sn(IV)-Fe(III) and Sn(IV)-Ni(II) associated with lignocaine as counter cation were synthesized. The synthetic routes for all the complexes were similar. The complexes were characterized by elemental analyses, molar conductance, magnetic susceptibility, UV-Visible, IR, 1HNMR, 13CNMR, ESR and Mass spectral measurements. Tentative schemes for mass spectral fragmentation patterns of Sn(IV)-Fe(III) complex was proposed. Based on these studies, the complexes were represented by the general formulae, [SnCl6][FeCl4][LH]3, [CdCl6][MCl4][LH]4, where M=Cd(II) or Ni(II) and LH= lignocaine.
