The material described by LiCoVO4 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted LiO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra, corners with two equivalent V(1)O4 tetrahedra, and  an edgeedge with one V(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 67-69°. V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with six equivalent Co(1)O6 octahedra, corners with two equivalent Li(1)O4 tetrahedra, and  an edgeedge with one Li(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 50-54°. Co(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Li(1)O4 tetrahedra, corners with six equivalent V(1)O4 tetrahedra, and edges with two equivalent Co(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Li(1), one V(1), and one Co(1) atom. In the second O site, O(2) is bonded to one Li(1), one V(1), and two equivalent Co(1) atoms to form a mixture of distorted edge and corner-sharing OLiVCo2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
