The compound described by YbPO2 crystallizes in the tetragonal I4_1/amd space group. Yb(1) is bonded to six equivalent O(1) atoms to form edge-sharing YbO6 octahedra. P(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. O(1) is bonded to three equivalent Yb(1) and two equivalent P(1) atoms to form a mixture of distorted edge and corner-sharing OYb3P2 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
