The crystal structure described by Yb2SeO2 crystallizes in the trigonal P-3m1 space group. Yb(1) is bonded in a 4-coordinate geometry to three equivalent Se(1) and four equivalent O(1) atoms. Se(1) is bonded in a 6-coordinate geometry to six equivalent Yb(1) atoms. O(1) is bonded to four equivalent Yb(1) atoms to form a mixture of edge and corner-sharing OYb4 tetrahedra. is represented by the CIF file [CIF]
