The material structure described by ErCrO4 is Zircon-like structured and crystallizes in the tetragonal I4_1/a space group. Er(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Cr(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. O(1) is bonded in a distorted trigonal planar geometry to two equivalent Er(1) and one Cr(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
