Title: Materials Data on CdFe4Cu10(SnSe4)5 by Materials Project

Abstract

Fe4Cu10Cd(SnSe4)5 is Clathrate-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Fe3+ sites. In the first Fe3+ site, Fe3+ is bonded to four Se2- atoms to form FeSe4 tetrahedra that share corners with four SnSe4 tetrahedra and corners with eight CuSe4 tetrahedra. There are one shorter (2.41 Å) and three longer (2.42 Å) Fe–Se bond lengths. In the second Fe3+ site, Fe3+ is bonded to four Se2- atoms to form FeSe4 tetrahedra that share corners with four SnSe4 tetrahedra and corners with eight CuSe4 tetrahedra. There are three shorter (2.42 Å) and one longer (2.43 Å) Fe–Se bond lengths. There are five inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share a cornercorner with one FeSe4 tetrahedra, corners with three equivalent CdSe4 tetrahedra, corners with four CuSe4 tetrahedra, and corners with four equivalent SnSe4 tetrahedra. There are a spread of Cu–Se bond distances ranging from 2.39–2.41 Å. In the second Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent FeSe4 tetrahedra, corners with four CuSe4 tetrahedra, and corners withmore » four SnSe4 tetrahedra. There are three shorter (2.44 Å) and one longer (2.45 Å) Cu–Se bond lengths. In the third Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with four FeSe4 tetrahedra, corners with four CuSe4 tetrahedra, and corners with four SnSe4 tetrahedra.

There are one shorter (2.68 Å) and three longer (2.69 Å) Sn–Se bond lengths. In the third Sn+3.20+ site, Sn+3.20+ is bonded to four Se2- atoms to form SnSe4 tetrahedra that share corners with four equivalent FeSe4 tetrahedra and corners with eight CuSe4 tetrahedra. There are two shorter (2.69 Å) and two longer (2.70 Å) Sn–Se bond lengths. There are ten inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the second Se2- site, Se2- is bonded to two Cu1+, one Cd2+, and one Sn+3.20+ atom to form corner-sharing SeCdCu2Sn tetrahedra. In the third Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the fourth Se2- site, Se2- is bonded to one Fe3+, two equivalent Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the fifth Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the sixth Se2- site, Se2- is bonded to two equivalent Cu1+, one Cd2+, and one Sn+3.20+ atom to form corner-sharing SeCdCu2Sn tetrahedra. In the seventh Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the eighth Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the ninth Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra. In the tenth Se2- site, Se2- is bonded to one Fe3+, two Cu1+, and one Sn+3.20+ atom to form corner-sharing SeFeCu2Sn tetrahedra.« less
