MnNiN2 crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded to six equivalent N(1) atoms to form distorted edge-sharing MnN6 pentagonal pyramids. Ni(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a rectangular see-saw-like geometry to three equivalent Mn(1) and one Ni(1) atom.
MnNiN2 crystallizes in the hexagonal P6_3/mmc space group. Mn(1) is bonded to six equivalent N(1) atoms to form distorted edge-sharing MnN6 pentagonal pyramids. All Mn(1)-N(1) bond lengths are 1.92 Å. Ni(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Ni(1)-N(1) bond lengths are 1.82 Å. N(1) is bonded in a rectangular see-saw-like geometry to three equivalent Mn(1) and one Ni(1) atom.
