The material described by MnZn2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_1 space group. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with two equivalent Mn(1)N4 tetrahedra and corners with ten equivalent Zn(1)N4 tetrahedra. Zn(1) is bonded to one N(2) and three equivalent N(1) atoms to form ZnN4 tetrahedra that share corners with five equivalent Mn(1)N4 tetrahedra and corners with seven equivalent Zn(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent Mn(1) and two equivalent Zn(1) atoms to form NMn2Zn2 tetrahedra that share corners with two equivalent N(2)Mn2Zn2 tetrahedra and corners with ten equivalent N(1)MnZn3 tetrahedra. In the second N site, N(1) is bonded to one Mn(1) and three equivalent Zn(1) atoms to form NMnZn3 tetrahedra that share corners with five equivalent N(2)Mn2Zn2 tetrahedra and corners with seven equivalent N(1)MnZn3 tetrahedra. is represented by the CIF file [CIF]
