Synthesis and structure of a new heteronuclear (eta(6)-arene) tricarbonylchromium compound incorporating propargyl amine unit

Reaction of equimolar amounts of [Co-2(CO)(6)(dppm)] and [Cr(eta(6)-C6H5)(C=-CCH2NMe2)(CO)(3)] (1) in benzene gives the novel heterotrimetallic complex [Cr(eta(6)-C6H5){(mu(2)-eta(2)-C=CCH2NMe2)Co-2(CO)(4)(dppm)}(CO)(3)] (2) in 40% yield. The X-ray structure analysis of 2 reveals that the Cr(CO)(3) tripod adopts a nearly anti-eclipsed conformation. (C) 2002 Elsevier B.V. B.V. All rights reserved.
