Maurya, R. C. published the artcilePreparation and characterization of some novel cyanonitrosyl {CrNO}5 complexes of chromium involving biologically important 2-pyrazoline-5-one derivatives, Recommanded Product: 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, the publication is National Academy Science Letters (India) (1992), 15(9), 299-301, database is CAplus.
[Cr(NO)(CN)2(L)2(H2O)] (L = 1-(2′-chlorophenyl)-, 1-(4′-tolyl)-, or 1-(4′-nitrophenyl)-, and 1-(4′-sulfophenyl)-3-methyl-2-pyrazolin-5-one) were isolated as solids by the interaction of K3[Cr(NO)(CN)5].H2O with L. The complexes, which were characterized by elemental anal., magnetic measurements, molar conductances, TGA, ESR and IR spectral studies, contain chromium(I) in a low-spin d5-configuration. An octahedral structure is proposed for the complexes.
