【摘要】 使用C6H11CO2Na和bipy为配体与Mn(ClO4)2·6H2O在水热条件下反应,制备了双核化合物[Mn2(O2CC6H11)2(bipy)4](ClO4)2(C6H11CO2H=环己烷甲酸;bipy=2,2′-联吡啶)。在双核阳离子[Mn2(O2CC6H11)2(bipy)4]2+结构中,锰原子之间通过两个环己烷甲酸根采取顺-反构型连接。该双核分子之间通过π-π堆积和弱C-H…O的氢键形成一个三维超分子网状结构。磁性质研究表明,锰离子之间存在弱反铁磁性耦合。更多还原

【Abstract】 [Mn2(O2CC6H11)2(bipy)4](ClO4)2(C6H11CO2H =cyclohexanecarboxylic acid; bipy =2,2′-bipyridine) was synthesized under hydrothermal condition by reactions of Mn(ClO4)2·6H2O, C6H11CO2Na and bipy. In the dinuclear cation [Mn2(O2CC6H11)2(bipy)4]2 +, adjacent Mn atoms are linked together through two cyclohexanecarboxylate ligands in syn-anti bridging mode. The molecules are packed together through π-π stacking of the pyridyl groups and weak hydrogen bonding interactions of C-H … O into three-dimensional supramolecular network. Magnetic study indicates there exists weak antiferromagnetic interactions between the adjacent Mn髤 ions. CCDC: 748489.更多还原
