Fe2NiN2 crystallizes in the orthorhombic Pmmn space group. Fe(1) is bonded to five equivalent N(1) atoms to form a mixture of edge and corner-sharing FeN5 square pyramids. Ni(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to five equivalent Fe(1) and one Ni(1) atom to form a mixture of edge and corner-sharing NFe5Ni octahedra. The corner-sharing octahedral tilt angles range from 5-18°.
Fe2NiN2 crystallizes in the orthorhombic Pmmn space group. Fe(1) is bonded to five equivalent N(1) atoms to form a mixture of edge and corner-sharing FeN5 square pyramids. There are a spread of Fe(1)-N(1) bond distances ranging from 1.96-2.00 Å. Ni(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Ni(1)-N(1) bond lengths are 1.83 Å. N(1) is bonded to five equivalent Fe(1) and one Ni(1) atom to form a mixture of edge and corner-sharing NFe5Ni octahedra. The corner-sharing octahedral tilt angles range from 5-18°.
