Reactivity of bis[{2,6-(dimethylamino)methyl}phenyl]telluride with Pd(ii) and Hg(ii): isolation of the first Pd(ii) complex of an organotellurenium cation as a ligand

Abstract

Intramolecularly coordinated homoleptic diorganotelluride L2Te (6) [where L = 2,6-(Me2NCH2)2C6H3] was synthesized and its reactions with Pd(II) and Hg(II) precursors were explored. The reaction of 6 with SO2Cl2 and K2PdCl4 resulted in the formation of the first example of a Pd(II) complex, LTePdCl3 (7), with any organotellurenium cation (LTe+) as a ligand. When diorganotelluride 6 was reacted with HgCl2, the reaction afforded the tellurenium cation [LTe]2+[Hg2Cl4]2− (8). The reaction of 6 with [(PhCN)2PdCl2] afforded the Pd(II)–telluroether complex L2TePdCl2 (9). Diorganotelluride 6 and complexes (7–9) were characterized by single-crystal X-ray diffraction studies. The crystallographic studies suggested that in complex 7, the Te(II) center was ‘ambiphilic’ in nature in the sense that while Te(II) acted as a donor to the Pd(II) ion, at the same time, it accepted electrons from the N-donor side arms via secondary bonding interactions. The donation of electrons from Te(II) to Pd(II) in complex 7 was further substantiated by Natural Bond Order (NBO) analysis.
