Novel low-spin hexacoordinate mixed-ligand cyanonitrosyl chelates (having [CrNO]5 electron configuration(1) of the type [Cr(NO)(CN)2(B−B)(H2O)] have been prepared by reacting K3[Cr(NO)(CN)5]·H2O with 5-chloro-7-iodo-8-hydroxyquinolinesulphonamides, B−B, viz., CIHQPS (1), CIHQOTS (2), CIHQMTS (3), CIHQPTS (4), CIHQOEPS (5), CIHQPEPS (6), CIHQOMPS (7) or CIHQPMPS (8) in aqueous acetic medium. The resulting compounds have been characterized on the basis of elemental analyses, electrical conductances, magnetic measurements, thermogravimetric analysis, electronic, e.s.r. and i.r. spectral studies.
