Conformations of silicon-containing rings. Part 4. Gas-phase structure of 1,3,5trisilacyclohexane and comparison with cyclohexane and cyclohexasilane

In the course of vibrational spectroscopic investigations of DNA-metal interactions, the FTIR spectra of protiated and iminodeuterated solid tetrakis(imidazole)copper(II) acetate were recorded at room temperature and the boiling temperature of liquid nitrogen (RT and LNT, respectively) and studied together with its RT Raman spectrum. Bands due to the internal vibrations of the acetate groups and imidazole ligands, are assigned and correlated with the available structural data.
