The compound described by Re7B3 crystallizes in the hexagonal P6_3mc space group. There are three inequivalent Re sites. In the first Re site, Re(1) is bonded in a 3-coordinate geometry to three equivalent B(1) atoms. In the second Re site, Re(3) is bonded in a distorted L-shaped geometry to two equivalent B(1) atoms. In the third Re site, Re(2) is bonded in a 3-coordinate geometry to three equivalent B(1) atoms. B(1) is bonded in a 6-coordinate geometry to one Re(1), two equivalent Re(3), and three equivalent Re(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
