Materials Data on Yb2Cu3Te4(ClO3)4 by Materials Project
Cu3Yb2(TeO3)4Cl4 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of one Cu3Yb2(TeO3)4Cl4 sheet oriented in the (0, 0, 1) direction. Yb3+ is bonded in a 7-coordinate geometry to eight O2- atoms. There are a spread of Yb–O bond distances ranging from 2.32–2.91 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a distorted rectangular see-saw-like geometry to two O2- and two Cl1- atoms. Both Cu–O bond lengths are 1.87 Å. There are one shorter (2.19 Å) and one longer (2.21 Å) Cu–Cl bond lengths. In the second Cu2+ site, Cu2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.93–2.20 Å. There are two inequivalent Te4+ sites. In the first Te4+ site, Te4+ is bonded in a 3-coordinate geometry to four O2- atoms. There are a spread of Te–O bond distances ranging from 1.88–2.70 Å. In the second Te4+ site, Te4+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Te–O bond distances ranging from 1.89–1.94 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Yb3+ and two Te4+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Yb3+, two Cu2+, and one Te4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Yb3+ and one Te4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Yb3+, one Cu2+, and one Te4+ atom. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to one Yb3+, one Cu2+, and one Te4+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Yb3+, one Cu2+, and one Te4+ atom. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Cu2+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Cu2+ atom.
