Re3C is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to four equivalent Re(2) and four equivalent C(1) atoms to form a mixture of distorted corner, face, and edge-sharing ReRe4C4 tetrahedra. In the second Re site, Re(2) is bonded in a distorted body-centered cubic geometry to eight equivalent Re(1) atoms. C(1) is bonded in a body-centered cubic geometry to eight equivalent Re(1) atoms.
