(Re3ClII)2− Anion and Other Trinuclear Complexes of Re (III)

Abstract

THE nature of the chloroanion of trivalent rhenium has been of interest for several years in view of a possible spin-paired tetrahedral stereochemistry1. However, recent studies of the crystal structure of the compound of composition CsReCl4 have established the existence of an anion (Re3Cl12)3− with a triangular arrangement of strongly bonded rhenium atoms2,3. (The most recent communication3 of the configuration of the (Re3Cl12)3− anion reports bond-lengths and angles which agree with our own refined values within experimental error. As these results have been derived from more complete experimental data and refined further than our own (R = 7.3 per cent for 580 reflexions,compared with R = 14.7 per cent for 453 reflexions) they have been quoted in this communication.) An earlier investigation by one of us (J. E. F.), using a range of cations, led to the isolation of the complex (Ph4As)2Re3Cl11. We have now made an X-ray analysis of this compound and obtained results which complement those from the cæsium compound in a most interesting way.
