The first diphosphastibolyl complexes: synthesis and characterisation of [Ru(η5-C5R5)(η5-C2But2P2Sb)]; R = H or Me
Abstract
Treatment of the novel ring anion [C2But2P2Sb]– 4 with [Ru(ηC5R5)(MeCN)3]PF6, (R = H, Me), affords the compounds [Ru(η5-C5R5)(η5-C2But2P2Sb)](R = H 6, Me 7), which represent the first examples of complexes derived from a diphosphastioblyl ring; the X-ray crystal structure of 7 is described.
