Title: Materials Data on Al(MoS2)4 by Materials Project

Abstract

Al(MoS2)4 crystallizes in the trigonal R3m space group. The structure is three-dimensional. there are two inequivalent Mo+3.25+ sites. In the first Mo+3.25+ site, Mo+3.25+ is bonded to six S2- atoms to form distorted MoS6 octahedra that share corners with three equivalent AlS4 tetrahedra, edges with four equivalent MoS6 octahedra, and edges with two equivalent MoS6 pentagonal pyramids. There are a spread of Mo–S bond distances ranging from 2.34–2.63 Å. In the second Mo+3.25+ site, Mo+3.25+ is bonded to six S2- atoms to form distorted MoS6 pentagonal pyramids that share corners with three equivalent AlS4 tetrahedra and edges with six equivalent MoS6 octahedra. There are three shorter (2.37 Å) and three longer (2.64 Å) Mo–S bond lengths. Al3+ is bonded to four S2- atoms to form AlS4 tetrahedra that share corners with nine equivalent MoS6 octahedra and corners with three equivalent MoS6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 65°. All Al–S bond lengths are 2.29 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 3-coordinate geometry to three equivalent Mo+3.25+ atoms. In the second S2- site, S2- is bonded in a 3-coordinate geometry to three Mo+3.25+ atoms. In the third S2-more » site, S2- is bonded to three Mo+3.25+ and one Al3+ atom to form a mixture of distorted edge and corner-sharing SAlMo3 tetrahedra. In the fourth S2- site, S2- is bonded to three equivalent Mo+3.25+ and one Al3+ atom to form a mixture of distorted edge and corner-sharing SAlMo3 tetrahedra.« less
