The compound described by K2Yb2O3 crystallizes in the monoclinic P2_1/c space group. K(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(2) atoms. Yb(1) is bonded to one O(1) and three equivalent O(2) atoms to form a mixture of edge and corner-sharing YbO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded to four equivalent K(1) and two equivalent Yb(1) atoms to form corner-sharing OK4Yb2 octahedra. The corner-sharing octahedral tilt angles are 61°. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent K(1) and three equivalent Yb(1) atoms. is represented by the CIF card [CIF]
