The structure described by Cu2GeO4 is Spinel structured and crystallizes in the tetragonal I4_1/amd space group. Cu(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Ge(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 Cu(1) and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
