Materials Data on Co(MoS2)2 by Materials Project

Abstract

CoMo2S4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Mo3+ is bonded to six S2- atoms to form distorted MoS6 octahedra that share corners with six equivalent CoS6 octahedra, edges with six equivalent MoS6 octahedra, and a faceface with one CoS6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are a spread of Mo–S bond distances ranging from 2.37–2.60 Å. Co2+ is bonded to six S2- atoms to form CoS6 octahedra that share corners with twelve equivalent MoS6 octahedra, edges with two equivalent CoS6 octahedra, and faces with two equivalent MoS6 octahedra. The corner-sharing octahedra tilt angles range from 52–53°. There are two shorter (2.31 Å) and four longer (2.34 Å) Co–S bond lengths. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to three equivalent Mo3+ and two equivalent Co2+ atoms. In the second S2- site, S2- is bonded in a 4-coordinate geometry to three equivalent Mo3+ and one Co2+ atom.
