Vibrational Spectroscopic Study of 6-Aminouracil Tetracyanonickelate Complexes

6-Aminouracil Tetracyanonickelate Komplekslerinin Titreşim Spektroskopisi ile İncelenmesi

The FT-IR, FT-Raman and far-IR spectra of two dimensional coordination polymer compounds, M(6AU)2Ni(CN)4 (where M = Mn, Co, Ni and Cd; 6AU = 6-aminouracil = 4-amino-2,6-dihydroxypyrimidine) were reported for the first time. 6-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)42- ions bridged by M(6AU)22+ cations. Vibrational bands originated from both 6AU and Ni(CN)4 group were assigned.
