Summary

A new series of spin-paired hexa-coordinated mixed-ligand cyanonitrosyl complexes of chromium (having {CrNO}5 electron configuration(1)) of the type [Cr(NO)(CN)2(L)2(H2O)] (where L=4-methyl-2-pyrazoline-5-one(1), 2,3-dimethyl-1-phenyl-3-pyrazoline-5-one(2) or 4-dimethylamino-2,3-dimethyl-1-phenyl-3-pyrazoline-5-one(3) have been synthesized in the solid state by the interaction of potassium pentacyanonitrosylchromate(I) monohydrate, K3[Cr(NO)(CN)5]· H2O with L in aqueous acetic acid. The products, which have been characterized by elemental analyses, molar conductances, thermogravimetric analyses, magnetic measurements, electron spin resonance and infrared spectral studies, contain low-spin chromium(I). An octahedral structure has been suggested for the complexes.
