2,2,4,4,6,6-Hexabenzylcyclotristannatellurane, (Bn2SnTe)3. Synthesis and Structural Characterization of an Organometallic Single-Source Precursor to Phase-Pure, Polycrystalline SnTe

The title compound, (Bn 2 SnTe) 3, Bn = CH 2 C 6 H 5, was prepared in high yield by treating Bn 2 SnCl 2 with (NH 4 ) 2 Te. Details of the synthesis and characterization ( 1 H, 13 C, 119 Sn, and 125 Te NMR; IR, single-crystal XRD, and elemental analyses) are presented. (Bn 2 SnTe) 3 serves as an efficient single-source precursor to phase-pure cubic SnTe under mild conditions
