The compound described by Cd3(GaN2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. In the second Cd site, Cd(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted CdN4 trigonal pyramids that share corners with eight equivalent Ga(1)N4 tetrahedra. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GaN4 tetrahedra that share corners with two equivalent Ga(1)N4 tetrahedra, corners with four equivalent Cd(2)N4 trigonal pyramids, and  an edgeedge with one Ga(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cd(2), two equivalent Cd(1), and two equivalent Ga(1) atoms to form a mixture of distorted edge and corner-sharing NCd3Ga2 trigonal bipyramids. In the second N site, N(2) is bonded in a 4-coordinate geometry to one Cd(1), one Cd(2), and two equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
