The material described by Zn3(GaN2)2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 3-coordinate 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 ZnN4 tetrahedra 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 distorted GaN4 tetrahedra that share corners with two equivalent Ga(1)N4 tetrahedra, corners with four equivalent Zn(2)N4 tetrahedra, 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 Zn(2), two equivalent Zn(1), and two equivalent Ga(1) atoms to form a mixture of distorted corner and edge-sharing NZn3Ga2 trigonal bipyramids. In the second N site, N(2) is bonded in a 4-coordinate geometry to one Zn(1), one Zn(2), and two equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
