The crystal structure described by LaTb2RuO7 crystallizes in the orthorhombic Cmcm space group. Tb(1) is bonded to one O(3), two equivalent O(2), and four equivalent O(1) atoms to form distorted TbO7 pentagonal bipyramids that share corners with two equivalent Ru(1)O6 octahedra, corners with three equivalent Tb(1)O7 pentagonal bipyramids, edges with two equivalent Ru(1)O6 octahedra, and edges with two equivalent Tb(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 38°. La(1) is bonded in a body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. Ru(1) is bonded to two equivalent O(3) and four equivalent O(1) atoms to form RuO6 octahedra that share corners with two equivalent Ru(1)O6 octahedra, corners with four equivalent Tb(1)O7 pentagonal bipyramids, and edges with four equivalent Tb(1)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 37°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Tb(1), one La(1), and one Ru(1) atom to form distorted OLaTb2Ru trigonal pyramids that share corners with four equivalent O(2)La2Tb2 tetrahedra, corners with eight equivalent O(1)LaTb2Ru trigonal pyramids, edges with two equivalent O(2)La2Tb2 tetrahedra, and edges with two equivalent O(1)LaTb2Ru trigonal pyramids. In the second O site, O(2) is bonded to two equivalent Tb(1) and two equivalent La(1) atoms to form OLa2Tb2 tetrahedra that share corners with six equivalent O(2)La2Tb2 tetrahedra, corners with eight equivalent O(1)LaTb2Ru trigonal pyramids,  an edgeedge with one O(2)La2Tb2 tetrahedra, and edges with four equivalent O(1)LaTb2Ru trigonal pyramids. In the third O site, O(3) is bonded in a 4-coordinate geometry to two equivalent Tb(1) and two equivalent Ru(1) atoms. is represented by the CIF file [CIF]
