摘要：
The reaction between cis-[Ru(NO)(CH3CN)(bpy)(2)](3+) and a free NO2- gives an appreciable amount of the nitro species cis-[Ru(NO2)(CH3CN)(bpy)(2)](+). Although definitive evidence for the mechanistic illustration of the nitrosyl-to-nitro conversion is still unavailable, an oxide abstraction from NO2- to the nitrosyl ligand appears to be the key reaction. In addition, cis-[Ru(NO)(CH3C(O)NH)(bpy)(2)](2+) having an acetamide ligand is formed during the reaction. The structure of the complex, used as a starting material of the present reaction, was determined by single-crystal X-ray diffraction methods; for cis-[Ru(NO)(CH3CN)(bpy)(2)](ClO4)(3). CH3CN: FW = 823.91, monoclinic, P2(1)/n, a = 12.471(3), b = 15.041(7), c = 17.598(4) Angstrom, beta = 94.65(2)degrees, V = 3289(1) Angstrom(3), Z = 4, R = 0.081, R-w = 0.050.
