Title: Materials Data on La4Cu4Se3SO4 by Materials Project

Abstract

(LaO)4Cu4Se3S crystallizes in the tetragonal P4mm space group. The structure is two-dimensional and consists of one Cu4Se3S sheet oriented in the (0, 0, 1) direction and one LaO sheet oriented in the (0, 0, 1) direction. In the Cu4Se3S sheet, Cu1+ is bonded to three Se2- and one S2- atom to form a mixture of edge and corner-sharing CuSe3S tetrahedra. There are one shorter (2.52 Å) and two longer (2.53 Å) Cu–Se bond lengths. The Cu–S bond length is 2.42 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 4-coordinate geometry to four equivalent Cu1+ atoms. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to four equivalent Cu1+ atoms. S2- is bonded in a 4-coordinate geometry to four equivalent Cu1+ atoms. In the LaO sheet, there are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All La–O bond lengths are 2.38 Å. In the second La3+ site, La3+ is bonded in a 4-coordinate geometry to four equivalent O2- atoms. All La–O bond lengths are 2.39 Å.
