Title: Materials Data on Ta3AlC2 by Materials Project

Abstract

Ta3AlC2 is MAX Phase-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a 3-coordinate geometry to three equivalent Al and three equivalent C atoms. All Ta–Al bond lengths are 2.86 Å. All Ta–C bond lengths are 2.20 Å. In the second Ta site, Ta is bonded to six equivalent C atoms to form edge-sharing TaC6 octahedra. All Ta–C bond lengths are 2.22 Å. Al is bonded in a 12-coordinate geometry to six equivalent Ta atoms. C is bonded to six Ta atoms to form a mixture of edge and corner-sharing CTa6 octahedra. The corner-sharing octahedral tilt angles are 0°.
