Title: Materials Data on InGaCu2(TeSe)2 by Materials Project

Abstract

Cu2InGa(TeSe)2 is Clathrate-derived structured and crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to two equivalent Te2- and two equivalent Se2- atoms to form CuTe2Se2 tetrahedra that share corners with four equivalent CuTe2Se2 tetrahedra, corners with four equivalent InTe2Se2 tetrahedra, and corners with four equivalent GaTe2Se2 tetrahedra. Both Cu–Te bond lengths are 2.59 Å. Both Cu–Se bond lengths are 2.50 Å. In the second Cu1+ site, Cu1+ is bonded to two equivalent Te2- and two equivalent Se2- atoms to form CuTe2Se2 tetrahedra that share corners with four equivalent CuTe2Se2 tetrahedra, corners with four equivalent InTe2Se2 tetrahedra, and corners with four equivalent GaTe2Se2 tetrahedra. Both Cu–Te bond lengths are 2.58 Å. Both Cu–Se bond lengths are 2.46 Å. In3+ is bonded to two equivalent Te2- and two equivalent Se2- atoms to form InTe2Se2 tetrahedra that share corners with four equivalent GaTe2Se2 tetrahedra and corners with eight CuTe2Se2 tetrahedra. Both In–Te bond lengths are 2.82 Å. Both In–Se bond lengths are 2.69 Å.
