The crystal structure described by Pr2Ti2S2O5 crystallizes in the tetragonal I4/mmm space group. Pr(1) is bonded in a 9-coordinate geometry to five equivalent S(1) and four equivalent O(1) atoms. Ti(1) is bonded to one S(1), one O(2), and four equivalent O(1) atoms to form distorted corner-sharing TiSO5 square pyramids. S(1) is bonded in a 6-coordinate geometry to five equivalent Pr(1) and one Ti(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Pr(1) and two equivalent Ti(1) atoms to form a mixture of distorted edge and corner-sharing OPr2Ti2 trigonal pyramids. In the second O site, O(2) is bonded in a linear geometry to two equivalent Ti(1) atoms. is represented by the CIF card [CIF]
