The metathetical reactions between SnBr 4 and Li 2 [E'C(PPh 2 E) 2 ] in toluene produce the homoleptic tin(IV) complexes Sn[ E ′C(PPh 2 E ) 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(PPh 2 E ) 2 ] 2 ( E = E ′ = Se, 1a ), which was prepared previously by a different route.
