Materials Data on Re3B by Materials Project
Re3B crystallizes in the orthorhombic Cmcm space group. The structure is two-dimensional and consists of two Re3B sheets oriented in the (0, 1, 0) direction. there are two inequivalent Re sites. In the first Re site, Re is bonded in a 2-coordinate geometry to three equivalent B atoms. There are two shorter (2.25 Å) and one longer (2.59 Å) Re–B bond lengths. In the second Re site, Re is bonded in a distorted L-shaped geometry to two equivalent B atoms. Both Re–B bond lengths are 2.22 Å. B is bonded in a 6-coordinate geometry to eight Re atoms.
