X-ray crystallographic investigation of the title complex oxide composition reveals the presence of two phases. The first is a spinel phase which is somewhat consistent with Zn2SnO4 witha0=8·646 Å. The other phase has been identified as a non-spinel phase of LiMnSnO4, the presence of which was confirmed by synthesizing it and comparing its XRD pattern with that of the title composition. The exact composition of the two phases has been determined by intensity calculations. It seems that while cooperative J-T effect is responsible for the observed symmetry of LiMnSnO4, the distribution of phase along with separation of phases is attributed to the solubility limit of Sn4+ in such quaternary compositions.
