RuF3 is Upper Bainite-like structured and crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Ru3+ is bonded to six equivalent F1- atoms to form corner-sharing RuF6 octahedra. The corner-sharing octahedral tilt angles are 44°. All Ru–F bond lengths are 2.02 Å. F1- is bonded in a distorted bent 150 degrees geometry to two equivalent Ru3+ atoms.
RuF4 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of one RuF4 sheet oriented in the (1, 0, 0) direction. Ru4+ is bonded to six F1- atoms to form corner-sharing RuF6 octahedra. The corner-sharing octahedral tilt angles are 47°. There is two shorter (1.86 Å) and four longer (2.04 Å) Ru–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two equivalent Ru4+ atoms. In the second F1- site, F1- is bonded in a single-bond geometry to one Ru4+ atom.
RuF6 is Tungsten structured and crystallizes in the cubic Im-3m space group. The structure is zero-dimensional and consists of two 13693-08-8 molecules. Ru6+ is bonded in an octahedral geometry to six equivalent F1- atoms. All Ru–F bond lengths are 1.86 Å. F1- is bonded in a single-bond geometry to one Ru6+ atom.
