The structure described by Tb(BO2)3 crystallizes in the orthorhombic Pbcn space group. Tb(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. There are two inequivalent B sites. In the first B site, B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. In the second B site, B(2) is bonded in a tetrahedral geometry to two equivalent O(2) and two equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Tb(1) and one B(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Tb(1), one B(1), and one B(2) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Tb(1), one B(1), and one B(2) atom. is represented by the CIF file [CIF]
