The structure described by W2ZnSO3 crystallizes in the triclinic P-1 space group. There are four inequivalent W sites. In the first W site, W(1) is bonded in a distorted water-like geometry to one Zn(2) and one O(4) atom. In the second W site, W(2) is bonded in a distorted single-bond geometry to one Zn(2) atom. In the third W site, W(3) is bonded in a distorted single-bond geometry to one Zn(1) and one O(6) atom. In the fourth W site, W(4) is bonded in a distorted single-bond geometry to one Zn(1) and one O(2) atom. There are three inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a 6-coordinate geometry to two equivalent W(3), two equivalent W(4), and two equivalent O(3) atoms. In the second Zn site, Zn(2) is bonded in a 6-coordinate geometry to two equivalent W(1), two equivalent W(2), and two equivalent O(5) atoms. In the third Zn site, Zn(3) is bonded in a distorted tetrahedral geometry to one O(1), one O(2), one O(4), and one O(6) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to one O(3), one O(4), and one O(6) atom. In the second S site, S(2) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Zn(3) and one S(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to one W(4), one Zn(3), and one S(2) atom. In the third O site, O(3) is bonded in a single-bond geometry to one Zn(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a trigonal planar geometry to one W(1), one Zn(3), and one S(1) atom. In the fifth O site, O(5) is bonded in a single-bond geometry to one Zn(2) and one S(2) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one W(3), one Zn(3), and one S(1) atom. is represented by the CIF file [CIF]
