Some new compounds of Chromium (I), formed by the interaction of potassium pentacyano-nitrosylchromate(I) monohydrate, K3[Cr(NO)(CN)5].H2O with alkyl substituted pyridines like 2.4-, 2,6-, and 3,5-lutidines, 2,4,6-collidine and 2-methyl-5-ethyl pyridine in acetic acid-water medium have been prepared in solid state. The compounds have been characterised on the basis of elemental analyses, magnetic measurements, electron spin resonance, reflectance and infrared spectral studies. The complexes are of the empirical formula, [Cr(NO)(CN)2L2] (where L-alkyl substituted pyridine taken). A cyano-bridging linear, polymeric structures have been proposed for the complexes. Chromium(I) has a low-spin d5-configuration in these complexes.
