The Reaction of N,N'-bis-(3-pyridyl) ethylene-bis-urea (BPEBU) with ZnSO4 in 2 : 1 ligand : metal ratio in various crystallization solvents afforded four metal-organic frameworks (MOFs), namely [{Zn(H2O)(3)(SO4)(mu-BPEBU)}center dot EG center dot 2H(2)O](n) 2, [{Zn(mu-BPEBU)(2)(H2O)(2)}center dot SO4 2H(2)O center dot 2THF}(n)3, [{Zn(mu-BPEBU)(2)(H2O)(2)}center dot SO4 center dot 2H(2)O center dot 2acetone}(n)4 and [{Zn(mu-BPEBU)(2)(H2O)(2)}center dot SO4 center dot 2H(2)O center dot 2 (1,4-dioxane)}(n)5, which were mainly characterized by single cyrstal X-ray diffraction. MOFs 3-5 are found to be isomorphous. The study revealed that the crystallization solvents affected the structures; the single crystal structure of the free BPEBU was also discussed in the context of the conformation and ligating topology of the ligand found in the reported MOFs. When the MOFs syntheses were performed in a competitive environment wherein other oxo-counter anions such as NO3-, ClO4- and CF3SO3- were present, the isolated MOFs turned out to be the corresponding sulfate MOFs 2-4 indicating interesting sulfate selectivity.
