Materials Data on Na3AlTe3 by Materials Project
Abstract
Na3AlTe3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to six Te2- atoms to form distorted NaTe6 octahedra that share corners with six equivalent NaTe6 octahedra, corners with three equivalent AlTe4 tetrahedra, edges with three equivalent NaTe6 octahedra, an edgeedge with one AlTe4 tetrahedra, faces with two equivalent NaTe6 octahedra, and a faceface with one AlTe4 tetrahedra. The corner-sharing octahedra tilt angles range from 29–67°. There are a spread of Na–Te bond distances ranging from 3.19–3.73 Å. In the second Na1+ site, Na1+ is bonded in a 6-coordinate geometry to six Te2- atoms. There are a spread of Na–Te bond distances ranging from 3.14–3.72 Å. In the third Na1+ site, Na1+ is bonded to six Te2- atoms to form distorted NaTe6 octahedra that share corners with eight NaTe6 octahedra, corners with four equivalent AlTe4 tetrahedra, edges with five NaTe6 octahedra, and edges with two equivalent AlTe4 tetrahedra. The corner-sharing octahedra tilt angles range from 29–67°. There are a spread of Na–Te bond distances ranging from 3.22–3.80 Å. Al3+ is bonded to four Te2- atoms to form AlTe4 tetrahedra that share corners with sevenmore »
