The structure described by Mn(NiN)2 crystallizes in the orthorhombic Pnma space group. Mn(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 3-coordinate geometry to three equivalent N(2) atoms. In the second Ni site, Ni(2) is bonded in a square co-planar geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to two equivalent Mn(1) and two equivalent Ni(2) atoms. In the second N site, N(2) is bonded to one Mn(1), two equivalent Ni(2), and three equivalent Ni(1) atoms to form edge-sharing NMnNi5 octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
