Ru3F is alpha bismuth trifluoride structured and crystallizes in the cubic Fm-3m space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded to four equivalent Ru(2) and four equivalent F(1) atoms to form a mixture of edge, face, and corner-sharing RuRu4F4 tetrahedra. In the second Ru site, Ru(2) is bonded in a body-centered cubic geometry to eight equivalent Ru(1) atoms. F(1) is bonded in a body-centered cubic geometry to eight equivalent Ru(1) atoms.
