The crystal structure described by KNa4GeAs3 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 5-coordinate geometry to two equivalent As(3) and three equivalent As(1) atoms. There are four inequivalent Na sites. In the first Na site, Na(1) is bonded in a 7-coordinate geometry to two equivalent Ge(1), two equivalent As(3), and three equivalent As(2) atoms. In the second Na site, Na(2) is bonded to one As(1), one As(3), and two equivalent As(2) atoms to form corner-sharing NaAs4 tetrahedra. In the third Na site, Na(3) is bonded in a 7-coordinate geometry to two equivalent Ge(1), one As(2), two equivalent As(1), and two equivalent As(3) atoms. In the fourth Na site, Na(4) is bonded in a 7-coordinate geometry to two equivalent Ge(1), one As(3), two equivalent As(1), and two equivalent As(2) atoms. Ge(1) is bonded in a 9-coordinate geometry to two equivalent Na(1), two equivalent Na(3), two equivalent Na(4), one As(1), one As(2), and one As(3) atom. There are three inequivalent As sites. In the first As site, As(3) is bonded in a 9-coordinate geometry to two equivalent K(1), one Na(2), one Na(4), two equivalent Na(1), two equivalent Na(3), and one Ge(1) atom. In the second As site, As(1) is bonded in a 9-coordinate geometry to three equivalent K(1), one Na(2), two equivalent Na(3), two equivalent Na(4), and one Ge(1) atom.
