The crystal structure described by GeCN2 crystallizes in the hexagonal P6_3/mmc space group. Ge(1) is bonded to six equivalent N(1) atoms to form edge-sharing GeN6 octahedra. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 4-coordinate geometry to three equivalent Ge(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
