The compound described by ZnTi2O4 crystallizes in the orthorhombic Cmcm space group. Ti(1) is bonded to one O(2), two equivalent O(3), and three equivalent O(1) atoms to form TiO6 octahedra that share corners with three equivalent Ti(1)O6 octahedra, corners with six equivalent Zn(1)O6 pentagonal pyramids, edges with five equivalent Ti(1)O6 octahedra, and  an edgeedge with one Zn(1)O6 pentagonal pyramid. The corner-sharing octahedral tilt angles range from 0-51°. Zn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted ZnO6 pentagonal pyramids that share corners with twelve equivalent Ti(1)O6 octahedra, edges with two equivalent Ti(1)O6 octahedra, and faces with two equivalent Zn(1)O6 pentagonal pyramids. The corner-sharing octahedral tilt angles range from 27-72°. There are three inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Ti(1) and two equivalent Zn(1) atoms to form distorted OTi3Zn2 trigonal bipyramids that share corners with five equivalent O(2)Ti2Zn2 tetrahedra, corners with two equivalent O(1)Ti3Zn2 trigonal bipyramids,  an edgeedge with one O(2)Ti2Zn2 tetrahedra, and edges with five equivalent O(1)Ti3Zn2 trigonal bipyramids. In the second O site, O(2) is bonded to two equivalent Ti(1) and two equivalent Zn(1) atoms to form OTi2Zn2 tetrahedra that share corners with two equivalent O(2)Ti2Zn2 tetrahedra, corners with ten equivalent O(1)Ti3Zn2 trigonal bipyramids, and edges with two equivalent O(1)Ti3Zn2 trigonal bipyramids. In the third O site, O(3) is bonded in a square co-planar geometry to four equivalent Ti(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
