GdAsO4 is Zircon structured and crystallizes in the tetragonal I4_1/amd space group. The structure is three-dimensional. Gd3+ is bonded in a 8-coordinate geometry to eight equivalent O2- atoms. There are four shorter (2.36 Å) and four longer (2.47 Å) Gd–O bond lengths. As5+ is bonded in a tetrahedral geometry to four equivalent O2- atoms. All As–O bond lengths are 1.72 Å. O2- is bonded in a 3-coordinate geometry to two equivalent Gd3+ and one As5+ atom.
