摘要：

Dicarbonyl(eta(5)-N,N-dimethylcarbamoylcyclopentadienyl) nitrosylchromium (5) was prepared by the reaction of the corresponding acid chloride with dimethylamine. The structure of 5 has been determined by X-ray diffraction studies: space group, P-1; monoclinic; a = 6.406(7), b = 8.805(8), c = 10.710(10) angstrom, alpha = 91.73(8), beta = 93.67(8), gamma = 101.96(8)degrees; Z = 2. The exocyclic carbon is bent away from the chromium atom with a theta angle of -0.27 degrees. The nitrosyl group is cisoid to the exocyclic carbonyl carbon of the Cp(Cr) ring with a twist angle of 63.27 degrees. The chemical shifts of C(2,5) and C(3,4) on the Cp ring has been assigned using two-dimensional HETCOR NMR spectroscopy.
