Transition Metal Coordination Polymers with Trans-1,4-Cyclohexanedicarboxylate: Acidity-Controlled Synthesis, Structures and Properties.

ABSTRACT: Five trans-1,4-cyclohexanedicarboxylate (chdc^2-) metal-organic frameworks of transition metals were synthesized in aqueous systems. A careful control of pH, reaction temperature and solvent composition were shown to direct the crystallization of a particular compound. Isostructural [Co(H₂O)₄(chdc)]_n (1) and [Fe(H₂O)₄(chdc)]_n (2) consist of one-dimensional hydrogen-bonded chains. Compounds [Cd(H₂O)(chdc)]_n∙0.5nCH₃CN (3), [Mn₄(H₂O)₃(chdc)₄]_n (4) and [Mn₂(Hchdc)₂(chdc)]_n (5) possess three-dimensional framework structures. The compounds 1, 4 and 5<
