The compound described by KTcO2 crystallizes in the tetragonal I4_1/amd space group. K(1) is bonded to six equivalent O(1) atoms to form edge-sharing KO6 octahedra. Tc(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent K(1) and two equivalent Tc(1) atoms to form a mixture of distorted edge and corner-sharing OK3Tc2 square pyramids. is represented by the CIF card [CIF]
