SYNTHESIS, RAMAN AND NMR SPECTROSCOPY OF THE TRIMETALLIC COMPLEXES

Synthesis, Raman and NMR studies are presented for the new octahedral trimetallic complexes with composition , R = p-XC6H4; X = H, CH3O, F, Cl.Only the isomer containing the Cl3Sn-Ir-Hg-Cl fragment and trans phosphine ligands is observed.Force constants for the Ir-Sn and Ir-Hg bonds as well as 31P, 119Sn and 199Hg NMR data are reported.The presence of a spin-spin coupling constant of more than 40,000 Hz between the 199Hg and 119Sn atoms is shown to originate from a two-bond and not a one-bond interaction.
