NaAuGe crystallizes in the orthorhombic Imm2 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Ge(1) atoms. In the second Na site, Na(2) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Ge(1) atoms. Au(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), three equivalent Na(2), one Au(1), and three equivalent Ge(1) atoms. Ge(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), three equivalent Na(2), three equivalent Au(1), and one Ge(1) atom.
NaAuGe crystallizes in the orthorhombic Imm2 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Ge(1) atoms. There are two shorter (3.02 Å) and four longer (3.12 Å) Na(1)-Au(1) bond lengths. There are two shorter (3.23 Å) and four longer (3.31 Å) Na(1)-Ge(1) bond lengths. In the second Na site, Na(2) is bonded in a 12-coordinate geometry to six equivalent Au(1) and six equivalent Ge(1) atoms. There are four shorter (3.14 Å) and two longer (3.42 Å) Na(2)-Au(1) bond lengths. There are four shorter (3.08 Å) and two longer (3.11 Å) Na(2)-Ge(1) bond lengths. Au(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), three equivalent Na(2), one Au(1), and three equivalent Ge(1) atoms. The Au(1)-Au(1) bond length is 2.97 Å. There is one shorter (2.58 Å) and two longer (2.59 Å) Au(1)-Ge(1) bond lengths. Ge(1) is bonded in a 10-coordinate geometry to three equivalent Na(1), three equivalent Na(2), three equivalent Au(1), and one Ge(1) atom. The Ge(1)-Ge(1) bond length is 2.55 Å.
