Title: Materials Data on Cu2SnSe3 by Materials Project

Abstract

Cu2SnSe3 is Enargite-like structured and crystallizes in the monoclinic Cc space group. The structure is three-dimensional. there are four inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with five SnSe4 tetrahedra and corners with seven CuSe4 tetrahedra. There are a spread of Cu–Se bond distances ranging from 2.41–2.44 Å. In the second Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with five SnSe4 tetrahedra and corners with seven CuSe4 tetrahedra. There are a spread of Cu–Se bond distances ranging from 2.41–2.46 Å. In the third Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with five SnSe4 tetrahedra and corners with seven CuSe4 tetrahedra. There are a spread of Cu–Se bond distances ranging from 2.41–2.46 Å. In the fourth Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with five SnSe4 tetrahedra and corners with seven CuSe4 tetrahedra. There are a spread of Cu–Se bond distances ranging from 2.42–2.45 Å. There are two inequivalent Sn4+ sites. In the first Sn4+ site, Sn4+ is bondedmore » to four Se2- atoms to form SnSe4 tetrahedra that share corners with two equivalent SnSe4 tetrahedra and corners with ten CuSe4 tetrahedra. There are a spread of Sn–Se bond distances ranging from 2.60–2.69 Å. In the second Sn4+ site, Sn4+ is bonded to four Se2- atoms to form SnSe4 tetrahedra that share corners with two equivalent SnSe4 tetrahedra and corners with ten CuSe4 tetrahedra. There are a spread of Sn–Se bond distances ranging from 2.60–2.70 Å. There are six inequivalent Se2- sites. In the first Se2- site, Se2- is bonded to three Cu1+ and one Sn4+ atom to form corner-sharing SeCu3Sn tetrahedra. In the second Se2- site, Se2- is bonded to three Cu1+ and one Sn4+ atom to form corner-sharing SeCu3Sn tetrahedra. In the third Se2- site, Se2- is bonded to three Cu1+ and one Sn4+ atom to form corner-sharing SeCu3Sn tetrahedra. In the fourth Se2- site, Se2- is bonded to two Cu1+ and two Sn4+ atoms to form corner-sharing SeCu2Sn2 tetrahedra. In the fifth Se2- site, Se2- is bonded to two Cu1+ and two Sn4+ atoms to form corner-sharing SeCu2Sn2 tetrahedra. In the sixth Se2- site, Se2- is bonded to three Cu1+ and one Sn4+ atom to form corner-sharing SeCu3Sn tetrahedra.« less
