KCuO crystallizes in the tetragonal I4/mmm 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 corner and edge-sharing OK4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-12°.
KCuO crystallizes in the tetragonal I4/mmm space group. K(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two shorter (2.69 Å) and two longer (2.76 Å) K(1)-O(1) bond lengths. Cu(1) is bonded in a linear geometry to two equivalent O(1) atoms. Both Cu(1)-O(1) bond lengths are 1.82 Å. O(1) is bonded to four equivalent K(1) and two equivalent Cu(1) atoms to form a mixture of distorted corner and edge-sharing OK4Cu2 octahedra. The corner-sharing octahedral tilt angles range from 0-12°.
