Abstract

Tm2PbS4 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are eight inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded to six S2- atoms to form TmS6 octahedra that share a cornercorner with one TmS6 pentagonal pyramid, a cornercorner with one TmS5 square pyramid, a cornercorner with one TmS5 trigonal bipyramid, corners with two equivalent TmS4 trigonal pyramids, an edgeedge with one TmS5 square pyramid, and an edgeedge with one TmS4 trigonal pyramid. There are a spread of Tm–S bond distances ranging from 2.63–2.86 Å. In the second Tm3+ site, Tm3+ is bonded in a 5-coordinate geometry to five S2- atoms. There are a spread of Tm–S bond distances ranging from 2.58–2.89 Å. In the third Tm3+ site, Tm3+ is bonded to five S2- atoms to form TmS5 trigonal bipyramids that share a cornercorner with one TmS6 octahedra, a cornercorner with one TmS5 square pyramid, a cornercorner with one TmS4 trigonal pyramid, and an edgeedge with one TmS6 pentagonal pyramid. The corner-sharing octahedral tilt angles are 39°. There are a spread of Tm–S bond distances ranging from 2.67–2.74 Å. In the fourth Tm3+ site, Tm3+ is bonded to four S2- atoms to form distortedmore » TmS4 trigonal pyramids that share corners with two equivalent TmS6 octahedra, a cornercorner with one TmS5 square pyramid, an edgeedge with one TmS6 pentagonal pyramid, and an edgeedge with one TmS4 trigonal pyramid.
