Gd2GeMoO8 is Zircon-derived structured and crystallizes in the tetragonal I-4 space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. In the second Gd site, Gd(2) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Mo(1) is bonded in a tetrahedral geometry to four equivalent O(2) atoms. Ge(1) is bonded in a tetrahedral geometry to four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Gd(1), one Gd(2), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Gd(1), one Gd(2), and one Mo(1) atom.
