A single step synthesis of some cyanonitrosyl {CrNO}(5) complexes of chromium(I) involving multi-functional ligands directly from chromate(VI) in aqueous-aerobic medium

Novel mixed-ligand cyanonitrosyl complexes of chromium(I), formed by intera ction of tetracyanonitrosylchromate(I) anion, [Cr(NO)(CN)(4)](2-) with 8-hy droxyquinoline (8-HQ), benzothiazole (BZT), imidazole(IDL), methyl benzothi azole (MBZT) and pheniramine maleate (PHM) are described. The resulting mix ed-ligand complexes, which have been characterized by elemental analyses, m olar conductances, magnetic measurements, electron spin resonance, infrared and electronic spectral studies, have the compositions [Cr(NO)(CN)(2)(L)(2 )(H2O)], where L = BZT, MBZT or IDL and [Cr(NO)(CN)(2)(L-L)(H2O)] where L-L = 8-HQ or PHM. A cis- octahedral structure has been proposed for these com plexes.
