Materials Data on Y(Mo3S4)2 by Materials Project

Abstract

Y(Mo3S4)2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Y3+ is bonded in a body-centered cubic geometry to eight S2- atoms. There are two shorter (2.71 Å) and six longer (3.00 Å) Y–S bond lengths. Mo+2.17+ is bonded to five S2- atoms to form a mixture of edge and corner-sharing MoS5 square pyramids. There are a spread of Mo–S bond distances ranging from 2.42–2.59 Å. There are two inequivalent S2- sites. In the first S2- site, S2- is bonded in a 1-coordinate geometry to one Y3+ and three equivalent Mo+2.17+ atoms. In the second S2- site, S2- is bonded in a 5-coordinate geometry to one Y3+ and four equivalent Mo+2.17+ atoms.
