- Abstract
As a result of the interaction of a heterometallic pivalate complex [Li2Zn2(py)2(piv)6] (piv– is the pivalate anion, py is pyridine) with a naphthalene-1,4-dicarboxylic acid (H2ndc) solution in DMF, heterometallic metal-organic framework (MOF) (H2NMe2)[Li5Zn4(DMF)2(Hndc)2(ndc)6]·11DMF·2H2O (1) is obtained. Dimethylammonium is formed due to the hydrolysis of DMF. During the synthesis, both complex fragmentation and complete maintenance of the initial tetranuclear heterometallic moiety {Li2Zn2} are observed. In the interaction of the same molecular complex with a nitroterephthalic acid solution (H2NO2-bdc), (H2NMe2)[LiZn(NO2-bdc)2]·0.5DMF·0.5H2O MOF (2) is formed in which there is a partial destruction of the initial framework with the formation of a binuclear unit {LiZn}. By the interaction of the heterometallic [Zn2Eu(phen)2(OH)(piv)4(NO3)2] (phen is phenanthroline) complex with the solution of 1,3,5-benzenetricarboxylic acid (H3btc) in DMF, homometallic framework polymer [Zn3(phen)3(btc)2]·DMF·3H2O (3) is obtained. Complete decomposition of the trinuclear heterometallic moiety is observed here.
