摘要：

The ruthenium(I) amidinato complex [Ru{PhNC(Me)NPh}(CO)(3)](2), has been prepared by heating [Ru-3(CO)(12)] with the free amidine, PhNC(Me)NHPh, in boiling benzene under a carbon monoxide atmosphere, and by heating [{Ru(O(2)CMe)(CO)(2)}(2)](n) with free amidine and triethylamine in acetonitrile under carbon monoxide. The structure of [Ru{PhNC(Me)NPh}(CO)(3)](2) has been determined by X-ray diffraction methods. The binuclear complex has two Ru(CO)(3) units linked by an Ru-Ru bond [2.714(1) Angstrom] and a cis pair of bridging amidinato ligands. Variable temperature H-1 and C-13 {H-1} NMR spectra show evidence of hindered rotation about the N-phenyl bonds of the amidinate ligands. An attempt to prepare the corresponding propionamidinato derivative gave a product which is tentatively formulated as [Ru{PhNC(Et)NPh}(CO)(2)(HO(2)CMe)](2) on the basis of analytical and spectroscopic evidence.
