Five metal-organic frameworks derived from l-tartarate (l-tart=C4H4O6) and the divalent metal ions magnesium, zinc or copper have been prepared and structurally characterized. The frameworks were prepared from the reaction of potassium l-tartrate [KC4H5O6] with the appropriate metal salt in water solutions. The magnesium compound [Mg(l-tart)(H2O)⊃1.5H2O], 1, crystallizes as a two-dimensional 63 sheet
已经制备了五种衍生自1-酒石酸酯(1-tart = C 4 H 4 O 6)和二价金属离子镁,锌或铜的金属-有机骨架并对其进行了结构表征。框架是由酒石酸钾[KC 4 H 5 O 6 ]与适当的金属盐在水溶液中反应制得的。镁化合物[镁(1-馅饼)(H 2 O)⊃1.5H 2 O],1,结晶为二维6 3片结构。向包含Zn 2+的体系中添加发散的连接子分子4,4'-联吡啶(bipy)或反式-1,2-双吡啶基乙烯(bpe)和Cu 2+导致纯手性三维结构的形成[锌2(1-馅饼)2(biyp)(H 2 O)⊃5.25H 2 O],2,[铜(1-馅饼)(联吡啶)⊃2.33H 2 O],3,和[铜(1-馅饼)(BPE)⊃8H 2 O],5.从去除溶剂的水分子的3导致[铜(1-馅饼)(联吡啶)⊃0.2 H 2 O],4。2和5的类似实验结果导致构架分解,说明这些结构的稳定性对客体水分子的依赖性。这项研究报告
