3-dimethylviolurate). The complexes react with Na[NO2] in acidic aqueous solutions to afford a series of novel diamagnetic nitrosylruthenium complexes of the general type cis-[Ru(L–L)2(NO)X](L–L = bidentate H2va– or dmva–; X–= Cl–, Br–, or unidentate H2va– or dmva–). In water, acetomtrile, or dimethyl sulphoxide. the complexes cis-[Ru(L–;L)3(NO)] release the co-ordinated nitrosyl lirgand owing to the intramolecular
