Cd3(FeN2)2 crystallizes in the monoclinic C2/c space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing FeN4 tetrahedra. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. In the second Cd site, Cd(2) is bonded in a distorted bent 120 degrees geometry to two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Fe(1), one Cd(1), and one Cd(2) atom to form a mixture of distorted corner and edge-sharing NCd2Fe2 trigonal pyramids. In the second N site, N(2) is bonded to two equivalent Fe(1) and two equivalent Cd(1) atoms to form a mixture of distorted corner and edge-sharing NCd2Fe2 trigonal pyramids.
Cd3(FeN2)2 crystallizes in the monoclinic C2/c space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing FeN4 tetrahedra. There is one shorter (1.81 Å) and one longer (1.82 Å) Fe(1)-N(1) bond length. There is one shorter (1.75 Å) and one longer (1.78 Å) Fe(1)-N(2) bond length. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one N(1) and two equivalent N(2) atoms. The Cd(1)-N(1) bond length is 2.36 Å. There is one shorter (2.30 Å) and one longer (2.59 Å) Cd(1)-N(2) bond length. In the second Cd site, Cd(2) is bonded in a distorted bent 120 degrees geometry to two equivalent N(1) atoms. Both Cd(2)-N(1) bond lengths are 2.27 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Fe(1), one Cd(1), and one Cd(2) atom to form a mixture of distorted corner and edge-sharing NCd2Fe2 trigonal pyramids. In the second N site, N(2) is bonded to two equivalent Fe(1) and two equivalent Cd(1) atoms to form a mixture of distorted corner and edge-sharing NCd2Fe2 trigonal pyramids.
