Ba3(MnN2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and three equivalent N(1) atoms. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to two equivalent N(1) and four equivalent N(2) atoms. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of edge and corner-sharing MnN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one Ba(2), three equivalent Ba(1), and two equivalent Mn(1) atoms. In the second N site, N(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Ba(1), two equivalent Ba(2), and two equivalent Mn(1) atoms.

In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and three equivalent N(1) atoms. There is one shorter (2.69 Å) and one longer (3.05 Å) Ba(1)-N(2) bond length. There are a spread of Ba(1)-N(1) bond distances ranging from 2.80-3.03 Å. In the second Ba site, Ba(2) is bonded in a 6-coordinate geometry to two equivalent N(1) and four equivalent N(2) atoms. Both Ba(2)-N(1) bond lengths are 2.88 Å. There are two shorter (2.76 Å) and two longer (3.21 Å) Ba(2)-N(2) bond lengths. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of edge and corner-sharing MnN4 tetrahedra.
