资源简介:
MoC is Molybdenum Carbide MAX Phase-like structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Mo4+ is bonded to six C4- atoms to form a mixture of edge, face, and corner-sharing MoC6 octahedra. The corner-sharing octahedra tilt angles range from 0–46°. There are three shorter (2.18 Å) and three longer (2.23 Å) Mo–C bond lengths. 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. In the second C4- site, C4- is bonded to six equivalent Mo4+ atoms to form a mixture of distorted edge and corner-sharing CMo6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 2°.
