The structure described by K2Ti2O5 crystallizes in the monoclinic C2/m space group. K(1) is bonded in a 8-coordinate geometry to one O(1), two equivalent O(3), and five equivalent O(2) atoms. Ti(1) is bonded in a 5-coordinate geometry to one O(2), one O(3), and three equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to one K(1) and three equivalent Ti(1) atoms to form a mixture of distorted corner and edge-sharing OKTi3 trigonal pyramids. In the second O site, O(2) is bonded in a distorted single-bond geometry to five equivalent K(1) and one Ti(1) atom. In the third O site, O(3) is bonded in a linear geometry to four equivalent K(1) and two equivalent Ti(1) atoms. is represented by the CIF card [CIF]
