The material described by Na2GeS3O7 crystallizes in the triclinic P-1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 5-coordinate geometry to one O(2), one O(4), one O(5), one O(6), and one O(7) atom. In the second Na site, Na(2) is bonded to one O(1), one O(4), one O(5), and two equivalent O(3) atoms to form distorted edge-sharing NaO5 trigonal bipyramids. Ge(1) is bonded in a distorted single-bond geometry to two equivalent S(3) and one O(1) atom. There are three inequivalent S sites. In the first S site, S(1) is bonded in a bent 120 degrees geometry to one O(3) and one O(6) atom. In the second S site, S(2) is bonded in a distorted water-like geometry to one O(2) and one O(7) atom. In the third S site, S(3) is bonded in a distorted single-bond geometry to two equivalent Ge(1) and one O(5) atom. There are seven inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Na(2) and one Ge(1) atom. In the second O site, O(2) is bonded in a 3-coordinate geometry to one Na(1), one S(2), and one O(4) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to two equivalent Na(2) and one S(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Na(1), one Na(2), and one O(2) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one Na(1), one Na(2), and one S(3) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Na(1) and one S(1) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one Na(1) and one S(2) atom. is represented by the CIF file [CIF]
