Ti2CdO5 crystallizes in the orthorhombic Cmcm space group. Ti(1) is bonded to one O(3), two equivalent O(1), and three equivalent O(2) atoms to form a mixture of distorted edge and corner-sharing TiO6 octahedra. The corner-sharing octahedral tilt angles range from 32-35°. Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ti(1) and one Cd(1) atom. In the second O site, O(2) is bonded to three equivalent Ti(1) and one Cd(1) atom to form distorted OTi3Cd trigonal pyramids that share  a cornercorner with one O(3)Ti2Cd2 tetrahedra, corners with three equivalent O(2)Ti3Cd trigonal pyramids, edges with two equivalent O(3)Ti2Cd2 tetrahedra, and edges with two equivalent O(2)Ti3Cd trigonal pyramids. In the third O site, O(3) is bonded to two equivalent Ti(1) and two equivalent Cd(1) atoms to form distorted OTi2Cd2 tetrahedra that share corners with two equivalent O(3)Ti2Cd2 tetrahedra, corners with two equivalent O(2)Ti3Cd trigonal pyramids, and edges with four equivalent O(2)Ti3Cd trigonal pyramids.

The corner-sharing octahedral tilt angles range from 32-35°. The Ti(1)-O(3) bond length is 2.06 Å. There is one shorter (1.83 Å) and one longer (2.02 Å) Ti(1)-O(1) bond length. There are two shorter (1.96 Å) and one longer (2.29 Å) Ti(1)-O(2) bond length. Cd(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. Both Cd(1)-O(1) bond lengths are 2.18 Å. Both Cd(1)-O(2) bond lengths are 2.48 Å. Both Cd(1)-O(3) bond lengths are 2.26 Å. There are three inequivalent O sites.
