Na3MnN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. Mn(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing MnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted hexagonal bipyramidal geometry to six equivalent Na(1) and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent Mn(1) atoms.
Na3MnN2 crystallizes in the cubic Ia-3 space group. Na(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. The Na(1)-N(1) bond length is 2.55 Å. There is one shorter (2.32 Å) and one longer (2.45 Å) Na(1)-N(2) bond length. Mn(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing MnN4 tetrahedra. The Mn(1)-N(1) bond length is 2.00 Å. All Mn(1)-N(2) bond lengths are 2.12 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted hexagonal bipyramidal geometry to six equivalent Na(1) and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a 6-coordinate geometry to four equivalent Na(1) and two equivalent Mn(1) atoms.
