The crystal structure described by CuZn2N2 crystallizes in the monoclinic C2/m space group. Cu(1) is bonded in a distorted T-shaped 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 to one N(2) and three equivalent N(1) atoms to form a mixture of distorted corner and edge-sharing ZnN4 trigonal pyramids. In the second Zn site, Zn(2) is bonded in a trigonal planar geometry to one N(1) and two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Cu(1), one Zn(2), and three equivalent Zn(1) atoms to form distorted NZn4Cu trigonal bipyramids that share corners with two equivalent N(1)Zn4Cu trigonal bipyramids, corners with five equivalent N(2)Zn3Cu2 trigonal bipyramids,  an edgeedge with one N(2)Zn3Cu2 trigonal bipyramid, and edges with two equivalent N(1)Zn4Cu trigonal bipyramids. In the second N site, N(2) is bonded to two equivalent Cu(1), one Zn(1), and two equivalent Zn(2) atoms to form NZn3Cu2 trigonal bipyramids that share corners with two equivalent N(2)Zn3Cu2 trigonal bipyramids, corners with five equivalent N(1)Zn4Cu trigonal bipyramids,  an edgeedge with one N(2)Zn3Cu2 trigonal bipyramid, and  an edgeedge with one N(1)Zn4Cu trigonal bipyramid. is represented by the CIF file [CIF]
