Na2MnN2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. In the second Na site, Na(2) is bonded in a 5-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. Mn(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Na(2), and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a 5-coordinate geometry to one Na(1), three equivalent Na(2), and one Mn(1) atom.
Na2MnN2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. The Na(1)-N(2) bond length is 2.37 Å. Both Na(1)-N(1) bond lengths are 2.47 Å. In the second Na site, Na(2) is bonded in a 5-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. There is one shorter (2.63 Å) and one longer (2.78 Å) Na(2)-N(1) bond length. All Na(2)-N(2) bond lengths are 2.49 Å. Mn(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. The Mn(1)-N(2) bond length is 1.60 Å. There is one shorter (1.73 Å) and one longer (1.74 Å) Mn(1)-N(1) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 6-coordinate geometry to two equivalent Na(1), two equivalent Na(2), and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a 5-coordinate geometry to one Na(1), three equivalent Na(2), and one Mn(1) atom.
