Fe2CuN2 crystallizes in the tetragonal I4/mmm space group. Fe(1) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing FeN4 tetrahedra. Cu(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 5-coordinate geometry to four equivalent Fe(1) and one Cu(1) atom.
Fe2CuN2 crystallizes in the tetragonal I4/mmm space group. Fe(1) is bonded to four equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing FeN4 tetrahedra. All Fe(1)-N(1) bond lengths are 1.90 Å. Cu(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Cu(1)-N(1) bond lengths are 1.84 Å. N(1) is bonded in a 5-coordinate geometry to four equivalent Fe(1) and one Cu(1) atom.
