The material structure described by GdNbO4 crystallizes in the monoclinic C2/c space group. Gd(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Nb(1) is bonded in a 4-coordinate geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Gd(1) and two equivalent Nb(1) atoms. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Gd(1) and one Nb(1) atom. is represented by the CIF card [CIF]
