LiMnSbO4 is Spinel-derived structured and crystallizes in the tetragonal P4_322 space group. Li(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted LiO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Li(1)O6 octahedra, and edges with four equivalent Sb(1)O6 octahedra. Mn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form MnO4 tetrahedra that share corners with six equivalent Li(1)O6 octahedra and corners with six equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 53-64°. Sb(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SbO6 octahedra that share corners with six equivalent Mn(1)O4 tetrahedra, edges with two equivalent Sb(1)O6 octahedra, and edges with four equivalent Li(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Li(1), one Mn(1), and one Sb(1) atom to form distorted OLi2MnSb tetrahedra that share corners with six equivalent O(1)Li2MnSb tetrahedra, corners with six equivalent O(2)LiMnSb2 trigonal pyramids,  an edgeedge with one O(1)Li2MnSb tetrahedra, and edges with two equivalent O(2)LiMnSb2 trigonal pyramids. In the second O site, O(2) is bonded to one Li(1), one Mn(1), and two equivalent Sb(1) atoms to form distorted OLiMnSb2 trigonal pyramids that share corners with six equivalent O(1)Li2MnSb tetrahedra, corners with six equivalent O(2)LiMnSb2 trigonal pyramids, edges with two equivalent O(1)Li2MnSb tetrahedra, and  an edgeedge with one O(2)LiMnSb2 trigonal pyramid.
