MnWN2 crystallizes in the hexagonal P6_3mc space group. W(1) is bonded to three equivalent N(1) and three equivalent N(2) atoms to form distorted WN6 octahedra that share corners with six equivalent Mn(1)N4 tetrahedra, edges with six equivalent W(1)N6 octahedra, and edges with three equivalent Mn(1)N4 tetrahedra. Mn(1) is bonded to one N(2) and three equivalent N(1) atoms to form MnN4 tetrahedra that share corners with six equivalent W(1)N6 octahedra, corners with six equivalent Mn(1)N4 tetrahedra, and edges with three equivalent W(1)N6 octahedra. The corner-sharing octahedral tilt angles range from 27-57°. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal non-coplanar geometry to three equivalent W(1) and three equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a distorted rectangular see-saw-like geometry to three equivalent W(1) and one Mn(1) atom.
