The crystal structure described by Ge3N4 crystallizes in the hexagonal P6_3/m space group. Ge(1) is bonded to one N(1) and three equivalent N(2) atoms to form corner-sharing GeN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a trigonal planar geometry to three equivalent Ge(1) atoms. In the second N site, N(1) is bonded in a trigonal planar geometry to three equivalent Ge(1) atoms. is represented by the CIF card [CIF]
