Abstract
Three new metal-organic frameworks [Zn(Hibdc)2]·DMF (1), (H2NMe2)[Li2Zn3(H2O)(dmf)(Hbtc)3(btc)]·6DMF·H2O (2), and [Li2Zn2(H2O)2(bpp)(bpdc)3]·7DMF (3) are obtained in the interaction of heterometallic carboxylate complex [Li2Zn2(piv)6(py)2] with isophthalic (H2ibdc) and trimesic (H3btc) acids and in the presence of both 4,4′-biphenyldicarboxylic acid (H2bpdc) and 4,4′-bispyridylpropane (bpp). The structure of the obtained compounds is determined by the single crystal X-ray diffraction analysis. In the reactions studied the structure of the initial {Li2Zn2} fragment is not retained. A complicated fragmentation of this four-nuclear block occurs, including the formation of binuclear heterometallic dimers {LiZn}.
