The structure described by Ga2Ge3N4 crystallizes in the monoclinic C2/c space group. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing GaN4 trigonal pyramids. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. In the second Ge site, Ge(2) is bonded in a water-like geometry to two equivalent N(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a rectangular see-saw-like geometry to two equivalent Ga(1) and two equivalent Ge(1) atoms. In the second N site, N(2) is bonded to two equivalent Ga(1), one Ge(1), and one Ge(2) atom to form corner-sharing NGa2Ge2 tetrahedra. is represented by the CIF file [CIF]
