Abstract
A novel mixed-li gand cyanonitrosyl complex of chromium (having {CrNO}5 electron configuration1), formed by the interaction of potassium pentacyanonitrosylchromate(I) monohy-drate, K3[Cr(NO)(CN)5]. H2O, with analgin (1-phenyl-2, 3-dimethyl-5-pyrazolone-4-methylaminomethanesulphonate sodium monohydrate) has been isolated. The product, which has been characterized by elemental analyses, molar conductance, molecular weight determination, thermogravimetric analysis, magnetic measurement, electron spin resonance and infrared spectral studies, possesses the formula [Cr(NO)(CN)2(AGNa)2(H2O)] (where AGNa - analgin) and it contains chromium(I) in a lowspin d5 configuration. An octahedral structure, where CN is trans to CN and AGNa is trans to AGNa in equatorial positions, and NO is trans to water at the axial position, has been proposed for the complex.
