Materials Data on OsF5 by Materials Project
OsF5 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two OsF5 clusters. Os5+ is bonded to six F1- atoms to form corner-sharing OsF6 octahedra. The corner-sharing octahedra tilt angles range from 42–44°. There are a spread of Os–F bond distances ranging from 1.86–2.06 Å. There are ten inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. The F–Os bond length is 1.89 Å. In the third F1- site, F1- is bonded in a distorted bent 150 degrees geometry to two equivalent Os5+ atoms. In the fourth F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. The F–Os bond length is 1.89 Å. In the fifth F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. In the sixth F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. In the seventh F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. The F–Os bond length is 1.86 Å. In the eighth F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. The F–Os bond length is 1.86 Å. In the ninth F1- site, F1- is bonded in a single-bond geometry to one Os5+ atom. In the tenth F1- site, F1- is bonded in a bent 150 degrees geometry to two equivalent Os5+ atoms.
