发现用于金属有机框架（MOF）合成的新的无机构建单元仍然具有挑战性。我们假设在铟结构单元上引入X型卤素封端配体将产生一系列先前未知的框架，并且卤素的放置可能导致框架异构。在本文中，我们报告了三种新的MOFs的合成;两种（YCM-31和YCM-32）含有[In（CO2 R）3Cl]−二级结构单元（SBU），并且是彼此的框架异构体。第三种新的MOF，ZJU-28′，含有[In（CO2 R）4]− SBU，是已知的MOF ZJU-28的骨架异构体。讨论了通过铵阳离子模板作用控制这些异构体合成的条件，沿着讨论了它们形成的原理。
The discovery of new inorganic building units for metal–organic framework (MOF) synthesis remains challenging. We hypothesized that incorporation of X-type halogen capping ligands on indium-building units would yield a series of previously unknown frameworks and the placement of the halogen could lead to framework isomerism. Herein we report the synthesis of three new MOFs; two (YCM-31 and YCM-32) contain an [In(CO2R)3Cl]− secondary building unit (SBU) and are framework isomers of each other. A third new MOF, ZJU-28′, contains an [In(CO2R)4]− SBU and is a framework isomer of the known MOF ZJU-28. The conditions to control the syntheses of these isomers through ammonium-cation templation, along with the rationale for their formation are discussed.
