Re3H 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 in a 8-coordinate geometry to four equivalent Re(2) and four equivalent H(1) atoms. In the second Re site, Re(2) is bonded in a body-centered cubic geometry to eight equivalent Re(1) atoms. H(1) is bonded in a distorted body-centered cubic geometry to eight equivalent Re(1) atoms.
