摘要：
The heterobimetallic complex syn-[Cr(CO)(3)(mu,eta:eta-indenyl)Rh(COD)] was obtained by reaction of syn-[Cr(CO)(3)(mu,eta:eta-indenyl)Rh(CO)(2)] with COD. The stereochemistry was retained in the exchange reaction as confirmed by H-1 and C-13 NMR measurements and by X-ray diffractometric analysis. In spite of great distortion, the COD complex is quite stable. An unusual bonding interaction between the hybrid C=O orbitals of the Cr(CO)(3) group and the s-orbital of methine hydrogen atoms of COD is inferred on the basis of spectroscopic and X-ray structural data.
