The material structure described by Nd3RuO7 crystallizes in the orthorhombic Pnma space group. There are three inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a distorted body-centered cubic geometry to two equivalent O(2), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms. In the second Nd site, Nd(2) is bonded in a 7-coordinate geometry to one O(1), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms. In the third Nd site, Nd(3) is bonded to one O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form NdO7 pentagonal bipyramids that share corners with two equivalent Ru(1)O6 octahedra, corners with two equivalent Nd(3)O7 pentagonal bipyramids, and edges with two equivalent Ru(1)O6 octahedra. The corner-sharing octahedral tilt angles are 39°. Ru(1) is bonded to two equivalent O(1), two equivalent O(4), and two equivalent O(5) atoms to form RuO6 octahedra that share corners with two equivalent Ru(1)O6 octahedra, corners with two equivalent Nd(3)O7 pentagonal bipyramids, and edges with two equivalent Nd(3)O7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 36°. There are five inequivalent O sites. In the first O site, O(5) is bonded in a 3-coordinate geometry to one Nd(1), one Nd(2), one Nd(3), and one Ru(1) atom. In the second O site, O(1) is bonded in a 4-coordinate geometry to one Nd(2), one Nd(3), and two equivalent Ru(1) atoms. In the third O site, O(2) is bonded to two equivalent Nd(1) and two equivalent Nd(2) atoms to form ONd4 tetrahedra that share corners with two equivalent O(3)Nd4 tetrahedra, corners with four equivalent O(2)Nd4 tetrahedra, corners with four equivalent O(4)Nd3Ru trigonal pyramids,  an edgeedge with one O(3)Nd4 tetrahedra, and edges with two equivalent O(4)Nd3Ru trigonal pyramids.
