The compound described by Na5GeAs3 crystallizes in the monoclinic P2_1/c space group. There are five inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to one As(2), two equivalent As(1), and two equivalent As(3) atoms. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one As(1), two equivalent As(2), and two equivalent As(3) atoms. In the third Na site, Na(3) is bonded in a 5-coordinate geometry to one As(3), two equivalent As(1), and two equivalent As(2) atoms. In the fourth Na site, Na(4) is bonded to one As(2), one As(3), and two equivalent As(1) atoms to form a mixture of distorted corner and edge-sharing NaAs4 tetrahedra. In the fifth Na site, Na(5) is bonded to one As(1), one As(3), and two equivalent As(2) atoms to form a mixture of distorted corner and edge-sharing NaAs4 tetrahedra. Ge(1) is bonded in a 4-coordinate geometry to one As(1), one As(2), and two equivalent As(3) atoms. There are three inequivalent As sites. In the first As site, As(3) is bonded in a 9-coordinate geometry to one Na(3), one Na(4), one Na(5), two equivalent Na(1), two equivalent Na(2), and two equivalent Ge(1) atoms. In the second As site, As(1) is bonded in a 9-coordinate geometry to one Na(2), one Na(5), two equivalent Na(1), two equivalent Na(3), two equivalent Na(4), and one Ge(1) atom.
