摘要：
The oxo-bridged dinuclear rhenium(V) complex [(mu-O)[ReOCl(amp)}(2)] (1) was prepared by the reaction of trans-[ReOCl3(PPh3)(2)] and 6-amino-3-methyl-1-phenyl-4-azahept-2-ene-1-one (Hamp) in acetone. The characterization of 1 by elemental analysis, infrared and H-1 NMR spectroscopy and X-ray crystallography shows that amp is coordinated as a monoanionic NNO-donor chelate as an amino-amido ketone. However, the reaction of the similar ligand 7-amino-4,7-dimethyl-5-aza-3-octen-2-one (Hada) with [Re(CO)(5)Br] produced fac-[Re(CO)(3)Br(Hada)], with Hada coordinated as a neutral bidentate N,N-donor amino-imino-ketone.
