摘要

The cationic complex [ReO(ahp)_2(PPh_3)]~+ was isolated as the chloride salt from the reaction of trans-[ReOCl_2(PPh_3)_2] and 2-amino-3-hydroxypyridine (Hahp) in ethanol. Coordination of the chelates only occurs through the amino nitrogen and the phenolate oxygen of ahp~-. The X-ray crystal structure shows a distorted octahedral geometry, in which a phenolate oxygen coordinated trans to the oxo group and the rhenium atom is displaced by 0.2520(1) A out of the mean equatorial plane towards the oxo oxygen.
