The compound described by K2TiO3 crystallizes in the orthorhombic Cmcm space group. K(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. Ti(1) is bonded to one O(1) and four equivalent O(2) atoms to form distorted edge-sharing TiO5 trigonal bipyramids. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to six equivalent K(1) and one Ti(1) atom. In the second O site, O(2) is bonded to four equivalent K(1) and two equivalent Ti(1) atoms to form a mixture of distorted edge, corner, and face-sharing OK4Ti2 octahedra. The corner-sharing octahedral tilt angles range from 35-48°. is represented by the Crystallographic Information File (CIF) [CIF]
