LiMnNbO{sub 4}, the first quaternary compound in Li-Mn-Nb-O system, has been prepared by solid-state reaction in hydrogen atmosphere at 1050 deg. C. According to the X-ray Rietveld refinement results (R(F{sup 2})=0.0265, {chi}{sup 2}=2.765), it is isostructural with LiZnNbO{sub 4}: tetragonal, P4{sub 3}22, a=6.1858(1), c=8.5312(1) A, Z=4, spinel-derived, with Li and Nb ordered on octahedral sites and with Mn in tetrahedral coordination. - Graphical abstract: Structure of LiMnNbO{sub 4}: ball-and-stick model of the unit cell (Li-O bonds are not shown, Mn-O bonds are gray, Nb-O bonds are white)
