FT-IR spectroscopic study on some 4-(3-cyclohexen-1-yl)pyridine Metal(II) tetracyanonickelate complexes

Abstract

New Hofmann-type complexes in the form of M(4-Chpy)(2)Ni(CN)(4) [where 4-Chpy = 4-(3-cyclohexen-1-yl)pyridine and M = Ni, Co] were prepared in powder form, and their infrared spectra are reported in the range of 4000-400 cm(-1). The spectral findings suggest that these compounds are similar in structure to the Hofmann-type complexes, and their structure consists of polymeric layers vertical bar M-Ni(CN)(4)vertical bar(infinity) with the 4-(3-cyclohexen-1-yl)pyridine molecule bound to the metal atom(M).
