Materials Data on Fe(Mo3Se4)2 by Materials Project
Abstract
Fe(Mo3Se4)2 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are six inequivalent Mo+2.17+ sites. In the first Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share corners with four MoSe5 square pyramids, a cornercorner with one FeSe4 tetrahedra, edges with five MoSe5 square pyramids, and a faceface with one FeSe4 tetrahedra. There are a spread of Mo–Se bond distances ranging from 2.55–2.73 Å. In the second Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share corners with four MoSe5 square pyramids, corners with two equivalent FeSe4 tetrahedra, and edges with five MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.56–2.70 Å. In the third Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share corners with four MoSe5 square pyramids, corners with two equivalent FeSe4 tetrahedra, and edges with five MoSe5 square pyramids. There are a spread of Mo–Se bond distances ranging from 2.57–2.72 Å. In the fourth Mo+2.17+ site, Mo+2.17+ is bonded to five Se2- atoms to form MoSe5 square pyramids that share corners with four MoSe5 square pyramids, cornersmore »
