Materials Data on CuTeO5 by Materials Project

CuTeO5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. Cu is bonded to five O atoms to form distorted corner-sharing CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.92–2.21 Å. Te is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Te–O bond distances ranging from 1.81–2.44 Å. There are five inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to one Cu, one Te, and one O atom. The O–O bond length is 1.34 Å. In the second O site, O is bonded in a distorted trigonal planar geometry to one Cu and two equivalent Te atoms. In the third O site, O is bonded in a bent 120 degrees geometry to one Cu and one Te atom. In the fourth O site, O is bonded in a distorted trigonal planar geometry to two equivalent Cu and one O atom. In the fifth O site, O is bonded in a single-bond geometry to one Te atom.
