KGe2N3 crystallizes in the orthorhombic Cmc2_1 space group. K(1) is bonded in a 5-coordinate geometry to two equivalent N(1) and three equivalent N(2) atoms. Ge(1) is bonded to one N(2) and three equivalent N(1) atoms to form corner-sharing GeN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a 2-coordinate geometry to three equivalent K(1) and two equivalent Ge(1) atoms. In the second N site, N(1) is bonded in a distorted trigonal planar geometry to one K(1) and three equivalent Ge(1) atoms.
