CuGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Cu(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CuN4 tetrahedra that share corners with four equivalent Cu(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with four equivalent Ge(1)N4 tetrahedra and corners with eight equivalent Cu(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Cu(1) and two equivalent Ge(1) atoms to form corner-sharing NCu2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Cu(1) and two equivalent Ge(1) atoms to form corner-sharing NCu2Ge2 tetrahedra.
CuGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Cu(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CuN4 tetrahedra that share corners with four equivalent Cu(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. There is one shorter (2.01 Å) and one longer (2.03 Å) Cu(1)-N(1) bond length. There is one shorter (2.02 Å) and one longer (2.03 Å) Cu(1)-N(2) bond length. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with four equivalent Ge(1)N4 tetrahedra and corners with eight equivalent Cu(1)N4 tetrahedra. There is one shorter (1.88 Å) and one longer (1.89 Å) Ge(1)-N(1) bond length. Both Ge(1)-N(2) bond lengths are 1.88 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Cu(1) and two equivalent Ge(1) atoms to form corner-sharing NCu2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Cu(1) and two equivalent Ge(1) atoms to form corner-sharing NCu2Ge2 tetrahedra.
