Phonons in isostructural compounds CuxM1?x(HCOO)2?2H2O (M = Mn, Co, Ni, Zn, and Cd): a Raman scattering study

The Raman spectra of isostructural compounds CuxM1−x(HCOO)2·2H2O (M = Mn, Co, Ni, Zn, and Cd) at room temperature are presented. The phonons observed were assigned on the basis of formate and water group vibrations and correlations with previous data reported for other formates. The influence of metal–guest ion substitution is discussed in the system Cu0.53Mn0.47(HCOO)2·2H2O when Mn is replaced by Cd. Copyright © 2002 John Wiley & Sons, Ltd.
