Description
Summary:[Ru(N,O-hia)(bpy)2]+ (I) and [Ru(N,O-hia)(bpy)(py)2]+ (II) (hia: CH3COC(NO)COCH3-) were prepared by the reactions of cis-[Ru(NO)(OH2)(bpy)2]3+ and cis-[Ru(NO)(OH)(bpy)(py)2]2+ with acetylacetone(Hacac) respectively. An X-ray structure analysis shows that the products have the identical nitroso ligand. Electrochemical behaviors of the complexes differ dramatically: I underwent an ECEC reaction, which could be illustrated as involving a structural rearrangement of the Ru-hia bonding, but II did not show such behavior and a typical reversible one-electron redox nature was found.
