Title: Materials Data on MoC by Materials Project

Abstract

MoC is Molybdenum Carbide MAX Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. there are two inequivalent Mo4+ sites. In the first Mo4+ site, Mo4+ is bonded to six C4- atoms to form a mixture of edge and corner-sharing MoC6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are three shorter (2.13 Å) and three longer (2.26 Å) Mo–C bond lengths. In the second Mo4+ site, Mo4+ is bonded to six equivalent C4- atoms to form a mixture of distorted edge and corner-sharing MoC6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 2°. All Mo–C bond lengths are 2.19 Å. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded to six equivalent Mo4+ atoms to form a mixture of edge and corner-sharing CMo6 octahedra. The corner-sharing octahedral tilt angles are 5°. In the second C4- site, C4- is bonded to six Mo4+ atoms to form a mixture of face, edge, and corner-sharing CMo6 octahedra. The corner-sharing octahedra tilt angles range from 5–48°.
