Abstract

The compound Te[OTe(C8H8)(S2P(OEt)2)]6(1), an unexpected hydrolysis product of C8H8Te[S2P(OEt)2]2, was subsequently synthesized under very mild conditions and appears to be the first organotellurium compound containing both tellurium(IV) and tellurium(VI). Crystals of 1 are triclinic, space group P1̅: a = 14.287 (2), b = 14.579 (2), c = 14.652 (2) Å; α = 85.30 (1), β= 84.36 (1), γ = 60.20 (1)°; Z = 1. The central Te(VI) atom is surrounded octahedrally by six oxygen atoms, which bridge to Te(IV) centers. Each Te(IV) center is coordinated asymmetrically by a dithiophosphate ligand. The sulfur atom of the longer Te-S bond also forms a secondary interaction with an adjacent Te(IV) atom within th..
