On the number of uncoordinated water molecules in the open-framework coordination compound, bis(1,2,4,5-benzenetetracarboxylato)dihydroxytetraaquapentacobalt(II) x-hydrate, and the crystal structure of the isomorphous decahydrated zinc(II) analog

Abstract: The formula unit of bis(1,2,4,5-benzenetetracarboxylato)dihydroxytetraaquapentazinc(II) decahydrate includes 10 uncoordinated water molecules; the compound is isomorphous with the reported [Co₅(C₁₀H₂O₈)₂(OH)₂(H₂O)₄]·xH₂O analog [Gutschke, Price, Powell & Wood (2001). Eur. J. Inorg. Chem. pp. 2739-2741], for which x is most probably 10. The asymmetric unit is one-half of the formula unit, with one Zn atom lying on an inversion center.
