The crystal structure described by ErO3 crystallizes in the hexagonal P6_3/m space group. Er(1) is bonded in a 9-coordinate geometry to nine equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to three equivalent Er(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
