Abstract

The metathetical reactions between SnBr4 and Li2[E'C(PPh2E)2] in toluene produce the homoleptic tin(IV) complexes Sn[E′C(PPh2E)2]2 [E = E′ = S (1b); E = S, E′ = Se (1c)], which were isolated as red crystals and structurally characterized by X-ray crystallography. The metrical parameters of these octahedral complexes are compared with those of the all-selenium analog Sn[E′C(PPh2E)2]2 (E = E′ = Se, 1a), which was prepared previously by a different route.
