Abstract

Mo15Sn3Se19 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are nine inequivalent Mo2+ sites. In the first Mo2+ site, Mo2+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share a cornercorner with one SnSe6 octahedra, corners with four MoSe5 square pyramids, and edges with three MoSe5 square pyramids. The corner-sharing octahedral tilt angles are 59°. There are a spread of Mo–Se bond distances ranging from 2.54–2.72 Å. In the second Mo2+ site, Mo2+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share a cornercorner with one SnSe6 octahedra, corners with four MoSe5 square pyramids, and edges with three MoSe5 square pyramids. The corner-sharing octahedral tilt angles are 55°. There are a spread of Mo–Se bond distances ranging from 2.54–2.74 Å. In the third Mo2+ site, Mo2+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share corners with four MoSe5 square pyramids, an edgeedge with one SnSe6 octahedra, and edges with three MoSe5 square pyramids.
