Popis: The reaction of InCl3 with NaSePh in ethanol followed by addition of PPh4C1 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.
