The material described by AgGe2N3 crystallizes in the orthorhombic Cmc2_1 space group. Ag(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted AgN4 tetrahedra that share corners with two equivalent Ag(1)N4 tetrahedra and corners with ten equivalent Ge(1)N4 tetrahedra. Ge(1) is bonded to one N(2) and three equivalent N(1) atoms to form GeN4 tetrahedra that share corners with five equivalent Ag(1)N4 tetrahedra and corners with seven equivalent Ge(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent Ag(1) and two equivalent Ge(1) atoms to form distorted NAg2Ge2 tetrahedra that share corners with two equivalent N(2)Ag2Ge2 tetrahedra and corners with ten equivalent N(1)AgGe3 trigonal pyramids. In the second N site, N(1) is bonded to one Ag(1) and three equivalent Ge(1) atoms to form distorted NAgGe3 trigonal pyramids that share corners with five equivalent N(2)Ag2Ge2 tetrahedra and corners with seven equivalent N(1)AgGe3 trigonal pyramids. is represented by the CIF card [CIF]
