FeZn2N2 crystallizes in the monoclinic C2/m space group. Fe(1) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(2) atoms. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted T-shaped geometry to one N(2) and two equivalent N(1) atoms. In the second Zn site, Zn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing ZnN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 5-coordinate geometry to one Fe(1), two equivalent Zn(1), and two equivalent Zn(2) atoms. In the second N site, N(2) is bonded to two equivalent Fe(1), one Zn(1), and two equivalent Zn(2) atoms to form a mixture of corner and edge-sharing NZn3Fe2 trigonal bipyramids.
FeZn2N2 crystallizes in the monoclinic C2/m space group. Fe(1) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(2) atoms. The Fe(1)-N(1) bond length is 1.85 Å. There is one shorter (1.82 Å) and one longer (1.90 Å) Fe(1)-N(2) bond length. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a distorted T-shaped geometry to one N(2) and two equivalent N(1) atoms. The Zn(1)-N(2) bond length is 2.12 Å. Both Zn(1)-N(1) bond lengths are 2.01 Å. In the second Zn site, Zn(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing ZnN4 trigonal pyramids. There is one shorter (2.00 Å) and one longer (2.52 Å) Zn(2)-N(1) bond length. Both Zn(2)-N(2) bond lengths are 2.07 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 5-coordinate geometry to one Fe(1), two equivalent Zn(1), and two equivalent Zn(2) atoms.
