title: Bis(2-amino-benzothia-zol-3-ium) bis-(7-oxabicyclo-[2.2.1]heptane-2,3-dicarboxyl-ato-κ(3)O(2),O(3),O(7))zincate hexa-hydrate.
abstract: In the title hydrated mol-ecular salt, (C(7)H(7)N(2)S)(2)[Zn(C(8)H(8)O(5))(2)]·6H(2)O, which is isotypic with its Mn(II), Co(II) and Ni(II) analogues, the Zn(2+) ion lies on a crystallographic inversion centre and a distorted ZnO(6) octa-hedral coordination geometry arises from the two doubly deprotonated O,O',O''-tridentate ligands. In the crystal, the components are linked by N-H⋯O(a), N-H⋯O(w), O(w)-H⋯O(a) and O(w)-H⋯O(w) hydrogen bonds (w = water and a = anion).
