GdBO3 crystallizes in the trigonal R32 space group. Gd(1) is bonded in a 8-coordinate geometry to two equivalent O(2) and six equivalent O(1) atoms. B(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing BO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Gd(1) and one B(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent Gd(1) and two equivalent B(1) atoms.
