The compound described by Er(PO)2 crystallizes in the tetragonal I4_1/amd space group. Er(1) is bonded in a distorted linear geometry to four equivalent P(1) and two equivalent O(1) atoms. P(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent Er(1) and one O(1) atom. O(1) is bonded in a bent 150 degrees geometry to one Er(1) and one P(1) atom. is represented by the CIF card [CIF]
