The structure described by 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. is represented by the CIF file [CIF]
