Vibrational Spectra of Tetragermanates of the Type Ln2CuGe4O12 (Ln = Lanthanide or Y)

The infrared and Raman spectra of a series of tetrametagermanates of composition Ln2CuGe4O12 (with Ln=Eu–Lu and Y), containing a Ge4O128- ring, were recorded and assigned on the basis of their structural characteristics. Force constants and mean amplitudes of vibration for the terminal GeO2 groups w...

Sumario:The infrared and Raman spectra of a series of tetrametagermanates of composition Ln2CuGe4O12 (with Ln=Eu–Lu and Y), containing a Ge4O128- ring, were recorded and assigned on the basis of their structural characteristics. Force constants and mean amplitudes of vibration for the terminal GeO2 groups were also estimated.
