The structure described by Na2Ge2S5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to one S(1), one S(5), two equivalent S(2), and two equivalent S(4) atoms. In the second Na site, Na(2) is bonded in a 6-coordinate geometry to two equivalent S(2), two equivalent S(4), and two equivalent S(5) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded to one S(1), one S(5), and two equivalent S(2) atoms to form corner-sharing GeS4 tetrahedra. In the second Ge site, Ge(2) is bonded to one S(3), one S(4), and two equivalent S(2) atoms to form corner-sharing GeS4 tetrahedra. There are five inequivalent S sites. In the first S site, S(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na(1) and two equivalent Ge(1) atoms. In the second S site, S(2) is bonded in a distorted water-like geometry to one Na(1), one Na(2), one Ge(1), and one Ge(2) atom. In the third S site, S(3) is bonded in a water-like geometry to two equivalent Ge(2) atoms. In the fourth S site, S(4) is bonded to two equivalent Na(1), two equivalent Na(2), and one Ge(2) atom to form distorted SNa4Ge square pyramids that share corners with six equivalent S(5)Na3Ge trigonal pyramids and edges with two equivalent S(4)Na4Ge square pyramids. In the fifth S site, S(5) is bonded to one Na(1), two equivalent Na(2), and one Ge(1) atom to form SNa3Ge trigonal pyramids that share corners with six equivalent S(4)Na4Ge square pyramids and corners with two equivalent S(5)Na3Ge trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
