The crystal structure and some reactions of bis(cyclo-octa-1,5-diene)-iridiumtrichlorotin

Abstract

The compound [Ir(SnCl₃)(C₈H₁₂)₂] has been shown by X-ray crystal analysis to contain five-co-ordinate iridium in a distorted trigonal bipyramidal environment of four double bonds and one tin atom. Reaction of this compound with (o-Ph₂As·C₆H₄)₃As, QAS, gives [Ir(SnCl₃)(QAS)] which can be oxidised to [IrCl(SnCl₃)(QAS)]Cl.
