Title: Materials Data on Al2Te3 by Materials Project

Abstract

Al2Te3 crystallizes in the monoclinic P2_1/c space group. The structure is two-dimensional and consists of two Al2Te3 sheets oriented in the (0, 0, 1) direction. there are four inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing AlTe4 tetrahedra. There are a spread of Al–Te bond distances ranging from 2.57–2.71 Å. In the second Al3+ site, Al3+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing AlTe4 tetrahedra. There are a spread of Al–Te bond distances ranging from 2.59–2.69 Å. In the third Al3+ site, Al3+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing AlTe4 tetrahedra. There are a spread of Al–Te bond distances ranging from 2.58–2.72 Å. In the fourth Al3+ site, Al3+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing AlTe4 tetrahedra. There are a spread of Al–Te bond distances ranging from 2.59–2.70 Å. There are six inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to three Al3+ atoms. In the second Te2- site, Te2- is bonded inmore » a 3-coordinate geometry to three Al3+ atoms. In the third Te2- site, Te2- is bonded in a distorted trigonal non-coplanar geometry to three Al3+ atoms. In the fourth Te2- site, Te2- is bonded in a distorted L-shaped geometry to two Al3+ atoms. In the fifth Te2- site, Te2- is bonded in a 3-coordinate geometry to three Al3+ atoms. In the sixth Te2- site, Te2- is bonded in a distorted L-shaped geometry to two Al3+ atoms.« less
