The paper describes the synthesis and properties of Triphenyltelluronium haloplumbates (II). [(Ph3Te)+]2[PbCI4]2–, [Ph3Te]+[PbBr3]– and [Ph3Te]+[PbI3]– type products are obtained by reactions of Ph3TeX with PbX2 in presence of HX (X ═ Cl, Br, I respectively). Conductivity, molecular weight determinations and 1H nmr data are consistent with their dissociation in dilute solution as Ph3Te+ and PbCl42– or Ph3Te+ and PbBr3- or PbI3 units. The absence of Te–Pb and Te–X vibrations in the far i. r. spectra of these compounds also supports their formulation as ionic compounds.
