Materials Data on Te2H2O3F4 by Materials Project
H2Te2O3F4 crystallizes in the orthorhombic Fdd2 space group. The structure is zero-dimensional and consists of eight H2Te2O3F4 clusters. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. Te4+ is bonded in a distorted rectangular see-saw-like geometry to two O2- and two F1- atoms. There is one shorter (1.92 Å) and one longer (1.95 Å) Te–O bond length. There are one shorter (1.99 Å) and one longer (2.04 Å) Te–F bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two equivalent Te4+ atoms. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one H1+ and one Te4+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted single-bond geometry to one Te4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Te4+ atom.
