CrGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CrN4 tetrahedra that share corners with four equivalent Cr(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 Cr(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Cr(1) and two equivalent Ge(1) atoms to form corner-sharing NCr2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Cr(1) and two equivalent Ge(1) atoms to form corner-sharing NCr2Ge2 tetrahedra.

Cr(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CrN4 tetrahedra that share corners with four equivalent Cr(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. There is one shorter (2.12 Å) and one longer (2.13 Å) Cr(1)-N(1) bond length. There is one shorter (2.06 Å) and one longer (2.08 Å) Cr(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 Cr(1)N4 tetrahedra. There is one shorter (1.88 Å) and one longer (1.89 Å) Ge(1)-N(1) bond length. There is one shorter (1.90 Å) and one longer (1.91 Å) Ge(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Cr(1) and two equivalent Ge(1) atoms to form corner-sharing NCr2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Cr(1) and two equivalent Ge(1) atoms to form corner-sharing NCr2Ge2 tetrahedra.
