MnN crystallizes in the monoclinic Pm space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one N(1) and four equivalent N(2) atoms to form distorted MnN5 trigonal bipyramids that share corners with six equivalent Mn(2)N4 tetrahedra, corners with four equivalent Mn(1)N5 trigonal bipyramids, edges with two equivalent Mn(2)N4 tetrahedra, and edges with four equivalent Mn(1)N5 trigonal bipyramids. In the second Mn site, Mn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with four equivalent Mn(2)N4 tetrahedra, corners with six equivalent Mn(1)N5 trigonal bipyramids, and edges with two equivalent Mn(1)N5 trigonal bipyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Mn(1) and two equivalent Mn(2) atoms. In the second N site, N(2) is bonded to two equivalent Mn(2) and four equivalent Mn(1) atoms to form a mixture of distorted corner, face, and edge-sharing NMn6 pentagonal pyramids.

The Mn(1)-N(1) bond length is 1.90 Å. There are two shorter (2.12 Å) and two longer (2.17 Å) Mn(1)-N(2) bond lengths. In the second Mn site, Mn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with four equivalent Mn(2)N4 tetrahedra, corners with six equivalent Mn(1)N5 trigonal bipyramids, and edges with two equivalent Mn(1)N5 trigonal bipyramids. There is one shorter (1.74 Å) and one longer (1.75 Å) Mn(2)-N(1) bond length. Both Mn(2)-N(2) bond lengths are 1.95 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Mn(1) and two equivalent Mn(2) atoms. In the second N site, N(2) is bonded to two equivalent Mn(2) and four equivalent Mn(1) atoms to form a mixture of distorted corner, face, and edge-sharing NMn6 pentagonal pyramids.
