The compound described by MnZn(GaSe2)4 crystallizes in the monoclinic C2 space group. Mn(1) is bonded to two equivalent Se(1) and two equivalent Se(3) atoms to form MnSe4 tetrahedra that share corners with four equivalent Ga(1)Se4 tetrahedra and corners with four equivalent Ga(2,3)Se4 tetrahedra. Zn(1) is bonded to two equivalent Se(2) and two equivalent Se(4) atoms to form ZnSe4 tetrahedra that share corners with four equivalent Ga(1)Se4 tetrahedra and corners with four equivalent Ga(2,3)Se4 tetrahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded to one Se(1), one Se(2), one Se(3), and one Se(4) atom to form GaSe4 tetrahedra that share corners with two equivalent Mn(1)Se4 tetrahedra; corners with two equivalent Zn(1)Se4 tetrahedra; and corners with four equivalent Ga(2,3)Se4 tetrahedra. In the second Ga site, Ga(2,3) is bonded to two equivalent Se(2) and two equivalent Se(3) atoms to form GaSe4 tetrahedra that share corners with two equivalent Mn(1)Se4 tetrahedra, corners with two equivalent Zn(1)Se4 tetrahedra, and corners with four equivalent Ga(1)Se4 tetrahedra. There are four inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to one Mn(1); one Ga(1); and one Ga(2,3) atom. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to one Zn(1); one Ga(1); and one Ga(2,3) atom. In the third Se site, Se(3) is bonded in a trigonal non-coplanar geometry to one Mn(1); one Ga(1); and one Ga(2,3) atom. In the fourth Se site, Se(4) is bonded in a trigonal non-coplanar geometry to one Zn(1); one Ga(1); and one Ga(2,3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
