The crystal structure described by Ru7B3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Ru sites. In the first Ru site, Ru(2) is bonded in a 3-coordinate geometry to three equivalent B(1) atoms. In the second Ru site, Ru(1) is bonded in a 3-coordinate geometry to three equivalent B(1) atoms. In the third Ru site, Ru(3) is bonded in a distorted water-like geometry to two equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to one Ru(2), two equivalent Ru(3), and three equivalent Ru(1) atoms. is represented by the CIF file [CIF]
