Materials Data on SbI(OF4)2 by Materials Project

Abstract

SbI(OF4)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two SbI(OF4)2 clusters. Sb is bonded to two O and four F atoms to form SbO2F4 octahedra that share corners with two equivalent IO2F4 octahedra. The corner-sharing octahedral tilt angles are 46°. There are one shorter (2.09 Å) and one longer (2.10 Å) Sb–O bond lengths. There is three shorter (1.89 Å) and one longer (1.90 Å) Sb–F bond length. There are two inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Sb and one I atom. The O–I bond length is 1.84 Å. In the second O site, O is bonded in a distorted bent 120 degrees geometry to one Sb and one I atom. The O–I bond length is 1.84 Å. I is bonded to two O and four F atoms to form IO2F4 octahedra that share corners with two equivalent SbO2F4 octahedra. The corner-sharing octahedral tilt angles are 46°. All I–F bond lengths are 1.86 Å. There are eight inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Sb atom. In the second F site, F is bonded in a single-bond geometry to one I 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 single-bond geometry to one Sb atom. In the fifth F site, F is bonded in a single-bond geometry to one I atom. In the sixth F site, F is bonded in a single-bond geometry to one I atom. In the seventh F site, F is bonded in a single-bond geometry to one I atom. In the eighth F site, F is bonded in a single-bond geometry to one Sb atom.
