Title: Materials Data on MnZn(GaSe2)4 by Materials Project

Abstract

MnZn(GaSe2)4 crystallizes in the tetragonal P-4 space group. The structure is three-dimensional. Mn2+ is bonded to four equivalent Se2- atoms to form MnSe4 tetrahedra that share corners with eight GaSe4 tetrahedra. All Mn–Se bond lengths are 2.52 Å. Zn2+ is bonded to four equivalent Se2- atoms to form ZnSe4 tetrahedra that share corners with eight GaSe4 tetrahedra. All Zn–Se bond lengths are 2.50 Å. There are three inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four Se2- atoms to form GaSe4 tetrahedra that share corners with two equivalent MnSe4 tetrahedra, corners with two equivalent ZnSe4 tetrahedra, and corners with four GaSe4 tetrahedra. All Ga–Se bond lengths are 2.46 Å. In the second Ga3+ site, Ga3+ is bonded to four equivalent Se2- atoms to form GaSe4 tetrahedra that share corners with four equivalent ZnSe4 tetrahedra and corners with four equivalent GaSe4 tetrahedra. All Ga–Se bond lengths are 2.46 Å. In the third Ga3+ site, Ga3+ is bonded to four equivalent Se2- atoms to form GaSe4 tetrahedra that share corners with four equivalent MnSe4 tetrahedra and corners with four equivalent GaSe4 tetrahedra. All Ga–Se bond lengths are 2.46 Å. There are two inequivalent Se2- sites. In the firstmore » Se2- site, Se2- is bonded in a trigonal non-coplanar geometry to one Zn2+ and two Ga3+ atoms. In the second Se2- site, Se2- is bonded in a trigonal non-coplanar geometry to one Mn2+ and two Ga3+ atoms.« less
