Materials Data on HoTeClO3 by Materials Project
HoTeO3Cl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ho3+ is bonded to five O2- and two equivalent Cl1- atoms to form a mixture of distorted edge and corner-sharing HoCl2O5 pentagonal bipyramids. There are a spread of Ho–O bond distances ranging from 2.18–2.37 Å. There are one shorter (2.80 Å) and one longer (2.86 Å) Ho–Cl bond lengths. Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There is one shorter (1.87 Å) and two longer (1.91 Å) Te–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ho3+ and one Te4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ho3+ and one Te4+ atom. Cl1- is bonded in a distorted bent 150 degrees geometry to two equivalent Ho3+ atoms.
