Abstract
The results of precise X-ray studies of the fumaronitrile complex of hydridocarbonylbis(triphenylphosphine)iridium and of the tetracyanoethylene complex of bromocarbonylbis(triphenylphosphine) iridium are presented and detailed comparisons are made with the results on other simple olefin-metal structures available in the literature.

Perhaps electronic factorsare important here, even though Cramer l8 has shown that there is essentially freerotation about the M- 11 bond in solution.CCAlthough in this paper we have chosen to discuss some aspects of molecularstructure within the Chatt-Dewar scheme, this should in no way be interpreted asan unqualified endorsement of the scheme. We are confident that suitably ingeniousarguments can be made within the framework of sigma bonding or excited statesto account for the observed trends.We are indebted to Prof. W. H. Baddley and Dr. W. C. Hamilton for makinginformation available to us in advance of publication.
