The polymeric title complex, [Co(C8H8O5)(H2O)2]n was synthesized by reaction of cobalt acetate with 7-oxabicyclo[2,2,1]heptane-2,3-dicarboxylic anhydride. The CoII ion is six-coordinated in a distorted octahedral environment, binding to two water O atoms, to the ether O atom of the bicycloheptane unit, to two carboxylate O atoms from two different carboxylate groups of the same anion and to one carboxylate O atom from a symmetry-related anion. The bridging character of the dianion leads to the formation of ribbons along [001]. The ribbons are linked into a layered network parallel to (010) by several O—H
O hydrogen-bonding interactions involving the coordinating water molecules as donors and the carboxylate O atoms of neighbouring ribbons as acceptors. The crystal under investigation was an inversion twin.

In the title hydrated molecular salt, (C7H7N2S)2[Zn(C8H8O5)2]·6H2O, which is isotypic with its MnII, CoII and NiII analogues, the Zn2+ ion lies on a crystallographic inversion centre and a distorted ZnO6 octahedral coordination geometry arises from the two doubly deprotonated O,O′,O′′-tridentate ligands. In the crystal, the components are linked by N—HOa, N—HOw, Ow—HOa and Ow—HOw hydrogen bonds (w = water and a = anion).

In the structure of the title complex, (C7H7N2S)2[Cd(C8H8O5)2]·6H2O, the CdII atom is located on an inversion center and is O,O′,O′′-chelated by two symmetry-related 7-oxabicyclo[2.2.1]heptane-2,3-dicarboxylate ligands in a distorted octahedral geometry. The 2-aminobenzothiazolium cation links with the Cd complex anion via N—HO hydrogen bonding. Extensive O—HO and N—HO hydrogen bonds involving lattice water molecules occur in the crystal structure.
