The material structure described by CsNaGe2 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cs sites. In the first Cs site, Cs(1) is bonded in a 8-coordinate geometry to one Na(1), one Na(2), one Ge(2), one Ge(4), two equivalent Ge(1), and two equivalent Ge(3) atoms. In the second Cs site, Cs(2) is bonded in a 10-coordinate geometry to one Na(1), one Na(2), two equivalent Ge(1), two equivalent Ge(2), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to one Cs(1), one Cs(2), one Ge(2), one Ge(3), two equivalent Ge(1), and two equivalent Ge(4) atoms. In the second Na site, Na(2) is bonded in a 7-coordinate geometry to one Cs(1), one Cs(2), one Ge(1), two equivalent Ge(2), two equivalent Ge(3), and two equivalent Ge(4) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Cs(2), one Na(2), two equivalent Na(1), one Ge(2), one Ge(3), and one Ge(4) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Cs(1), two equivalent Cs(2), one Na(1), two equivalent Na(2), one Ge(1), one Ge(3), and one Ge(4) atom. In the third Ge site, Ge(3) is bonded in a 10-coordinate geometry to two equivalent Cs(1), two equivalent Cs(2), one Na(1), two equivalent Na(2), one Ge(1), one Ge(2), and one Ge(4) atom. In the fourth Ge site, Ge(4) is bonded in a 10-coordinate geometry to one Cs(1), two equivalent Cs(2), two equivalent Na(1), two equivalent Na(2), one Ge(1), one Ge(2), and one Ge(3) atom. is represented by the Crystallographic Information File (CIF) [CIF]
