title: Materials Data on NiSb3XeF23 by Materials Project

description: XeF5NiSb3F18 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four XeF5 clusters and one NiSb3F18 framework. In each XeF5 cluster, Xe is bonded in a square pyramidal geometry to five F atoms. There is four shorter (1.96 Å) and one longer (1.97 Å) Xe–F bond length. There are five inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Xe atom. In the second F site, F is bonded in a single-bond geometry to one Xe atom. In the third F site, F is bonded in a single-bond geometry to one Xe atom. In the fourth F site, F is bonded in a single-bond geometry to one Xe atom. In the fifth F site, F is bonded in a single-bond geometry to one Xe atom. In the NiSb3F18 framework, there are two inequivalent Ni sites. In the first Ni site, Ni is bonded to six F atoms to form NiF6 octahedra that share corners with six SbF6 octahedra. The corner-sharing octahedra tilt angles range from 25–33°. There are two shorter (2.03 Å) and four longer (2.04 Å) Ni–F bond lengths. In the second Ni site, Ni is bonded to six F atoms to form NiF6 octahedra that share corners with six SbF6 octahedra. The corner-sharing octahedra tilt angles range from 20–29°. There are a spread of Ni–F bond distances ranging from 2.02–2.04 Å. There are three inequivalent Sb sites. In the first Sb site, Sb is bonded to six F atoms to form SbF6 octahedra that share corners with two NiF6 octahedra. The corner-sharing octahedra tilt angles range from 25–29°. There are a spread of Sb–F bond distances ranging from 1.89–1.98 Å. In the second Sb site, Sb is bonded to six F atoms to form SbF6 octahedra that share corners with two NiF6 octahedra. The corner-sharing octahedra tilt angles range from 22–27°. There are a spread of Sb–F bond distances ranging from 1.89–1.98 Å. In the third Sb site, Sb is bonded to six F atoms to form SbF6 octahedra that share corners with two NiF6 octahedra. The corner-sharing octahedra tilt angles range from 20–33°. There are a spread of Sb–F bond distances ranging from 1.89–1.97 Å. There are eighteen inequivalent F sites. In the first F site, F is bonded in a bent 150 degrees geometry to one Ni and one Sb atom. In the second F site, F is bonded in a single-bond geometry to one Sb atom. In the third F site, F is bonded in a single-bond geometry to one Sb atom. In the fourth F site, F is bonded in a bent 150 degrees geometry to one Ni and one Sb atom. In the fifth F site, F is bonded in a single-bond geometry to one Sb atom. In the sixth F site, F is bonded in a single-bond geometry to one Sb atom. In the seventh F site, F is bonded in a bent 150 degrees geometry to one Ni and one Sb atom. In the eighth F site, F is bonded in a single-bond geometry to one Sb atom. In the ninth F site, F is bonded in a single-bond geometry to one Sb atom. In the tenth F site, F is bonded in a bent 150 degrees geometry to one Ni and one Sb atom. In the eleventh F site, F is bonded in a single-bond geometry to one Sb atom. In the twelfth F site, F is bonded in a single-bond geometry to one Sb atom. In the thirteenth F site, F is bonded in a bent 150 degrees geometry to one Ni and one Sb atom. In the fourteenth F site, F is bonded in a single-bond geometry to one Sb atom. In the fifteenth F site, F is bonded in a single-bond geometry to one Sb atom. In the sixteenth F site, F is bonded in a bent 150 degrees geometry to one Ni and one Sb atom. In the seventeenth F site, F is bonded in a single-bond geometry to one Sb atom. In the eighteenth F site, F is bonded in a single-bond geometry to one Sb atom.
