Ru2BiO7 crystallizes in the orthorhombic I2_12_12_1 space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form RuO6 octahedra that share corners with two equivalent Ru(1)O6 octahedra, corners with four equivalent Ru(2)O6 octahedra, and edges with four equivalent Bi(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 43-47°. In the second Ru site, Ru(2) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form RuO6 octahedra that share corners with two equivalent Ru(2)O6 octahedra, corners with four equivalent Ru(1)O6 octahedra, and edges with two equivalent Bi(1)O8 hexagonal bipyramids. The corner-sharing octahedral tilt angles range from 32-47°. Bi(1) is bonded to two equivalent O(1), two equivalent O(3), two equivalent O(4), and two equivalent O(5) atoms to form distorted BiO8 hexagonal bipyramids that share edges with two equivalent Bi(1)O8 hexagonal bipyramids, edges with two equivalent Ru(2)O6 octahedra, and edges with four equivalent Ru(1)O6 octahedra. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ru(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent Ru(2) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Ru(1), one Ru(2), and one Bi(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Ru(1), one Ru(2), and one Bi(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to two equivalent Bi(1) atoms.
