Abstract

New crystalline \(\{\text{Mn}_{2}^{\text{II}}\text{Mn}_{2}^{\text{III}}\}\) tetranuclear cluster is prepared by the interaction of manganese(II) chloride with calix[4]arene 3 functionalized at the upper rim by distal p-(4-nitrophenyl)diazenyl and p-tert-butyl groups displaying different electronic effects and sizes. The structure of the cluster is studied by single-crystal XRD. Due to the presence of (4-nitrophenyl)diazenyl moieties at the upper rim of the macrocyclic ligand, the molecules of the tetranuclear \(\{\text{Mn}_{2}^{\text{II}}\text{Mn}_{2}^{\text{III}}\}\) clusters are involved in π-stacking interactions leading to the formation of 2D supramolecular layers affording a porous crystal packing.

基于杯的新型四核$$\text{\{Mn}_2^{\text{II}}\text{Mn}_2^{\text{III}}\}$$簇的合成和多孔晶体结构[4]芳烃在上缘被远端对-(4-硝基苯基)二氮烯基和对叔丁基官能化

摘要

新的晶体\(\{\text{Mn}_{2}^{\text{II}}\text{Mn}_{2}^{\text{III}}\}\)四核团簇由氯化锰(II)与杯[4]芳烃3的相互作用，杯[4]芳烃3在上缘通过远端对(4-硝基苯基)二氮烯基和对叔丁基官能化，显示出不同的电子效应和尺寸。通过单晶 XRD 研究了团簇的结构。由于大环配体上缘存在(4-硝基苯基)二氮烯基部分，四核分子\(\{\text{Mn}_{2}^{\text{II}}\text{ Mn}_{2}^{\text{III}}\}\)簇参与π堆积相互作用，导致形成二维超分子层，从而提供多孔晶体堆积。
