The material structure described by K3Gd(BO3)2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to one O(4), one O(5), and four equivalent O(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to one O(3), one O(4), one O(5), two equivalent O(2), and three equivalent O(1) atoms. Gd(1) is bonded to one O(2), one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form corner-sharing GdO7 pentagonal bipyramids. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(3), one O(4), and one O(5) atom. In the second B site, B(2) is bonded in a trigonal planar geometry to one O(2) and two equivalent O(1) atoms. There are five inequivalent O sites. In the first O site, O(2) is bonded in a 1-coordinate geometry to four equivalent K(2), one Gd(1), and one B(2) atom. In the second O site, O(3) is bonded to two equivalent K(2), two equivalent Gd(1), and one B(1) atom to form distorted corner-sharing OK2Gd2B trigonal bipyramids. In the third O site, O(4) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), one Gd(1), and one B(1) atom. In the fourth O site, O(5) is bonded in a distorted single-bond geometry to one K(1), two equivalent K(2), one Gd(1), and one B(1) atom. In the fifth O site, O(1) is bonded in a 1-coordinate geometry to two equivalent K(1), three equivalent K(2), one Gd(1), and one B(2) atom. is represented by the CIF card [CIF]
