Materials Data on Re2Te5 by Materials Project

Abstract

Re2Te5 crystallizes in the orthorhombic Pbca space group. The structure is two-dimensional and consists of two Re2Te5 sheets oriented in the (0, 0, 1) direction. there are three inequivalent Re5+ sites. In the first Re5+ site, Re5+ is bonded to five Te2- atoms to form edge-sharing ReTe5 square pyramids. There are a spread of Re–Te bond distances ranging from 2.71–2.75 Å. In the second Re5+ site, Re5+ is bonded to five Te2- atoms to form edge-sharing ReTe5 square pyramids. There are a spread of Re–Te bond distances ranging from 2.72–2.77 Å. In the third Re5+ site, Re5+ is bonded to five Te2- atoms to form edge-sharing ReTe5 square pyramids. There are a spread of Re–Te bond distances ranging from 2.71–2.76 Å. There are eight inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 7-coordinate geometry to three Re5+ atoms. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to three Re5+ atoms. In the third Te2- site, Te2- is bonded in a 1-coordinate geometry to one Re5+ atom. In the fourth Te2- site, Te2- is bonded in a square co-planar geometry to four Te2- atoms. There are two shorter (3.04 Å) and two longer (3.07 Å) Te–Te bond lengths. In the fifth Te2- site, Te2- is bonded in a 6-coordinate geometry to three Re5+ atoms. In the sixth Te2- site, Te2- is bonded in a 4-coordinate geometry to three Re5+ atoms. In the seventh Te2- site, Te2- is bonded in a 1-coordinate geometry to one Re5+ and one Te2- atom. In the eighth Te2- site, Te2- is bonded in a 1-coordinate geometry to one Re5+ and one Te2- atom.
