Materials Data on HoClO2 by Materials Project

Abstract

HoO2Cl crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Ho is bonded in a 9-coordinate geometry to six O and three equivalent Cl atoms. There are a spread of Ho–O bond distances ranging from 2.27–2.41 Å. There are two shorter (2.78 Å) and one longer (2.89 Å) Ho–Cl bond lengths. There are two inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to three equivalent Ho atoms. In the second O site, O is bonded in a distorted trigonal planar geometry to three equivalent Ho atoms. Cl is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ho atoms.
