The material structure described by Ru11B8 crystallizes in the orthorhombic Pbam space group. There are six inequivalent Ru sites. In the first Ru site, Ru(6) is bonded in a 4-coordinate geometry to one B(1), one B(3), one B(4), and two equivalent B(2) atoms. In the second Ru site, Ru(1) is bonded in a distorted square co-planar geometry to four equivalent B(1) atoms. In the third Ru site, Ru(2) is bonded in a 6-coordinate geometry to two equivalent B(1), two equivalent B(3), and two equivalent B(4) atoms. In the fourth Ru site, Ru(3) is bonded in a distorted trigonal non-coplanar geometry to one B(2) and two equivalent B(3) atoms. In the fifth Ru site, Ru(4) is bonded in a 6-coordinate geometry to two equivalent B(1), two equivalent B(3), and two equivalent B(4) atoms. In the sixth Ru site, Ru(5) is bonded in a 4-coordinate geometry to one B(3), one B(4), and two equivalent B(2) atoms. There are four inequivalent B sites. In the first B site, B(1) is bonded in a 7-coordinate geometry to one Ru(6), two equivalent Ru(1), two equivalent Ru(2), and two equivalent Ru(4) atoms. In the second B site, B(2) is bonded in a 7-coordinate geometry to one Ru(3), two equivalent Ru(5), two equivalent Ru(6), and two equivalent B(4) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to one Ru(5), one Ru(6), two equivalent Ru(2), two equivalent Ru(3), two equivalent Ru(4), and one B(4) atom. In the fourth B site, B(4) is bonded in a 9-coordinate geometry to one Ru(5), one Ru(6), two equivalent Ru(2), two equivalent Ru(4), one B(3), and two equivalent B(2) atoms. is represented by the CIF file [CIF]
