The material structure described by KCuO crystallizes in the tetragonal I-4m2 space group. K(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. O(1) is bonded to four equivalent K(1) and two equivalent Cu(1) atoms to form a mixture of distorted edge and corner-sharing OK4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 1-13°. is represented by the Crystallographic Information File (CIF) [CIF]
