VF3 is alpha bismuth trifluoride structured and crystallizes in the trigonal R3m space group. V(1) is bonded in a 11-coordinate geometry to three equivalent F(3), four equivalent F(1), and four equivalent F(2) atoms. All V(1)-F(3) bond lengths are 2.29 Å. There are three shorter (2.14 Å) and one longer (2.50 Å) V(1)-F(1) bond length. There are three shorter (2.14 Å) and one longer (2.50 Å) V(1)-F(2) bond length. There are three inequivalent F sites. In the first F site, F(1) is bonded to four equivalent V(1) and one F(3) atom to form distorted FV4F trigonal bipyramids that share corners with four equivalent F(2)V4 tetrahedra, corners with twelve equivalent F(1)V4F trigonal bipyramids, and edges with six equivalent F(2)V4 tetrahedra. The F(1)-F(3) bond length is 1.38 Å. In the second F site, F(2) is bonded to four equivalent V(1) atoms to form FV4 tetrahedra that share corners with twelve equivalent F(2)V4 tetrahedra, corners with four equivalent F(1)V4F trigonal bipyramids, and edges with six equivalent F(1)V4F trigonal bipyramids. In the third F site, F(3) is bonded in a 4-coordinate geometry to three equivalent V(1) and one F(1) atom.
