The syntheses and crystal structures of [PPh4] [In (SePh) 4] and [PPh4] [In(SePh)3(SeH)]
摘要:
The reaction of InCl3 with NaSePh in ethanol followed by addition of PPh4Cl affords tetraphenylphosphonium tetra (benzeneselenolato)indium(III), [PPh4][In(SePh)(4)] (1). Reaction of the [In(SePh4)](-) reaction mixture with NaBH4 and elemental sulfur followed by the addition of PPh4Cl yields tetraphenylphosphonium tri(benzeneselenolato)(hydroselenido)indium(III), [PPh4][In(SePh)(3)(SeH)] (2). The structures of 1 and 2, as determined from single-crystal X-ray data, feature well-separated cations;and anions with the In(III) centers of the anions tetrahedrally coordinated to four [SePh](-) ligands or three [SePh](-) ligands and one [SeH](-) ligand, respectively.
