Cr2TiO5 crystallizes in the monoclinic C2/c space group. Ti(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form TiO6 octahedra that share corners with two equivalent Ti(1)O6 octahedra, corners with six equivalent Cr(1)O6 octahedra, and edges with four equivalent Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-57°. Cr(1) is bonded to one O(1), two equivalent O(2), and three equivalent O(3) atoms to form CrO6 octahedra that share corners with three equivalent Ti(1)O6 octahedra, corners with four equivalent Cr(1)O6 octahedra,  an edgeedge with one Cr(1)O6 octahedra, edges with two equivalent Ti(1)O6 octahedra, and  a faceface with one Cr(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 43-55°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Ti(1) and two equivalent Cr(1) atoms to form distorted OTi2Cr2 trigonal pyramids that share corners with two equivalent O(1)Ti2Cr2 trigonal pyramids, corners with two equivalent O(3)TiCr3 trigonal pyramids, and edges with four equivalent O(3)TiCr3 trigonal pyramids. In the second O site, O(2) is bonded in a trigonal planar geometry to one Ti(1) and two equivalent Cr(1) atoms. In the third O site, O(3) is bonded to one Ti(1) and three equivalent Cr(1) atoms to form OTiCr3 trigonal pyramids that share  a cornercorner with one O(1)Ti2Cr2 trigonal pyramid, corners with three equivalent O(3)TiCr3 trigonal pyramids, edges with two equivalent O(1)Ti2Cr2 trigonal pyramids, and edges with two equivalent O(3)TiCr3 trigonal pyramids.
