Co-ordinatively unsaturated group 15 elements: the isolation and crystal structure of a novel dimeric dithiarsolidinium cation
Abstract
The first example of a dithiarsolidinium cation has a novel dimeric structure, while the spirocyclic bis(ethanediyldithio)phosphonium cation has been isolated from attempts to obtain the corresponding dithiaphospholidinium cation, both observations illustrating the importance of supplemental stabilisation for low-co-ordinate group 15 elements.
