Cr(FeN)3 crystallizes in the orthorhombic Cmcm space group. Cr(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a see-saw-like geometry to one N(2) and three equivalent N(1) atoms. In the second Fe site, Fe(2) is bonded in a see-saw-like 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 to one Cr(1), one Fe(2), and three equivalent Fe(1) atoms to form a mixture of edge and corner-sharing NCrFe4 trigonal bipyramids. In the second N site, N(2) is bonded to one Cr(1), two equivalent Fe(1), and two equivalent Fe(2) atoms to form a mixture of edge and corner-sharing NCrFe4 trigonal bipyramids.
Cr(FeN)3 crystallizes in the orthorhombic Cmcm space group. Cr(1) is bonded in a trigonal planar geometry to one N(2) and two equivalent N(1) atoms. The Cr(1)-N(2) bond length is 1.80 Å. Both Cr(1)-N(1) bond lengths are 1.80 Å. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a see-saw-like geometry to one N(2) and three equivalent N(1) atoms. The Fe(1)-N(2) bond length is 1.96 Å. There are two shorter (1.92 Å) and one longer (1.99 Å) Fe(1)-N(1) bond length. In the second Fe site, Fe(2) is bonded in a see-saw-like geometry to two equivalent N(1) and two equivalent N(2) atoms. Both Fe(2)-N(1) bond lengths are 1.96 Å. Both Fe(2)-N(2) bond lengths are 1.92 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cr(1), one Fe(2), and three equivalent Fe(1) atoms to form a mixture of edge and corner-sharing NCrFe4 trigonal bipyramids. In the second N site, N(2) is bonded to one Cr(1), two equivalent Fe(1), and two equivalent Fe(2) atoms to form a mixture of edge and corner-sharing NCrFe4 trigonal bipyramids.
