A new family of antimonates Li2Cr3−xMIIIxSbO8 (MIII = Al, Fe, Ga) was synthesized and studied by X-ray diffraction and ir spectroscopy. The Al-containing compounds exhibit a hexagonal close-packed structure similar to that of LiFeSnO4 ( a ⋍ 5.8,

A series of germanate spinels Zn2−x(Ni, Co)xGeO4 has been synthesized and investigated by X-ray diffractometry and infrared spectroscopy. Synthesis at 1200°C leads to cubic phases characterized by an inverse, disordered distribution of Ge and biva

A new family of complex antimonates MII4MIIISbVO8 has been synthesized and investigated by X-ray diffractometry and ir and Mossbauer spectroscopy. Many of these compounds possess a spinel structure, with a cation distribution which depends on the nat

The infrared spectrum of some LiX III O 2 compounds (X III = Al, Ga, Co, Cr, Rh, Sc) with an ordered distribution of Li and X III cations on octahedral sites has been investigated with the help of 6 Li- 7 Li isotopic replacement. The spectrum is esse

The i.r. spectrum of ordered spinels LiXIIIYIII4O8(XIII = Ga, Fe, In; YIII = Cr, Rh) are discussed and assigned with the help of 6Li-7Li isotopio shifts. Two bands only may be assigned to definite motions of specific cations or coordinated groups: on

The investigation of normal II-IV germanates, I-II-V vanadates and normal I-VI molybdate and tungstate spinels show that the high-frequency band of their i.r. spectrum must be assigned to a vibration of the tetrahedral group. A comparison is made wit

Isotopic shifts related to medium-weight cations (Mg, Ca, Ni, Zn, Or, Ge) have been observed in the vibrational spectrum of inorganic solids. It is possible, by this technique, to evidence the simultaneous participation of several cations to a given
