Materials Data on Ta2InC by Materials Project

Abstract

Ta2InC is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ta is bonded in a 3-coordinate geometry to three equivalent In and three equivalent C atoms. All Ta–In bond lengths are 3.04 Å. All Ta–C bond lengths are 2.19 Å. In is bonded to six equivalent Ta and six equivalent In atoms to form distorted InTa6In6 cuboctahedra that share corners with six equivalent InTa6In6 cuboctahedra, corners with six equivalent CTa6 octahedra, edges with six equivalent InTa6In6 cuboctahedra, edges with six equivalent CTa6 octahedra, and faces with six equivalent InTa6In6 cuboctahedra. The corner-sharing octahedral tilt angles are 20°. All In–In bond lengths are 3.17 Å. C is bonded to six equivalent Ta atoms to form CTa6 octahedra that share corners with six equivalent InTa6In6 cuboctahedra, edges with six equivalent InTa6In6 cuboctahedra, and edges with six equivalent CTa6 octahedra.
