Vibrational Spectroscopic Study of Two Dimensional Polymer Compounds of 5-Aminouracil

Abstract

In this study, FT-IR and FT-Raman spectra of two dimensional coordination polymer compounds, M(5AU)(2)Ni(CN)(4) (where M = Mn, Co, Ni, Zn and Cd; 5AU = 5-aminouracil i.e., 5-amino-2,4-dihydroxypyrimidine) were reported. 5-Aminouracil molecules are found to involve coordination through one of the pyrimidine ring nitrogen atoms. The spectral features suggest that the compounds are similar in structure to the Hofmann type two dimensional coordination polymer compounds, formed with Ni(CN)(4)(2-) ions bridged by M(5AU)(2)(2+) cations. Vibrational bands originated from both 5AU and Ni(CN)(4) group were assigned.
