Abstract

The reaction between BiI3, [PPh4]I and an excess of PMe2Ph afforded the ionic compound [PPh4][BiI4(PMe2Ph)2] the structure of which has been determined by X-ray crystallography. The anion [BiI4(PMe2Ph)2]- comprises an octahedral bismuth centre bonded to four iodines and two cis phosphine ligands, although there are some significant distortions from idealised octahedral coordination, the origins of which are discussed. From the reaction between SbBr3 and PEt3, the ionic complex [PEt3H][Sb2Br7(PEt3)2] was isolated, probably as a result of adventitious hydrolysis, and also characterised by X-ray crystallography. A discrete dinuclear anion [Sb2Br7(PEt3)2]- is present in this complex with a geometry best described as between face-shared bioctahedral and two square-based pyramids sharing a vertex.
