金属有机骨架（MOFs）的形成机制是一个新兴的领域，每一个新的发现都推动了该领域的发展。通常，研究集中在研究成核事件与先进的光谱和显微镜技术。综合理解所涉及的分子中间体及其在自组装中的作用的努力不太常见。在本文中，我们报告了MOF YCM-41（YCM = Youngstown Crystalline Material）的合成，其包含两种不同的In节点：一种是标准的[In（CO2 R）4]−，另一种是[In（CO2 R）3Cl]−。我们假设[In（CO2 R）3Cl]−是合成[In（CO2 R）4]−的机械中间体。此外，我们还报道了一维配位聚合物YCM-42的分离，它含有以前未报道的[In（CO2 R）2Cl 2]−结构单元。YCM-42的一维人字形结构可以在YCM-41中找到。最后，尝试合成这些结构的等网格版本导致了1-D配位聚合物YCM-51的合成，其含有[I...
The mechanism of formation of metal–organic frameworks (MOFs) is an emerging field, where each new discovery propels the field forward. Often, studies focus on studying nucleation events with advanced spectroscopy and microscopy techniques. Efforts to synthetically understand the molecular intermediates involved and their role in self-assembly are less common. Herein we report the synthesis of a MOF, YCM-41 (YCM = Youngstown Crystalline Material), that contains two different In-nodes: one the standard [In(CO2R)4]− and the second of [In(CO2R)3Cl]−. We hypothesize that the [In(CO2R)3Cl]− is a mechanistic intermediate in the synthesis of [In(CO2R)4]−. Additionally, we report the isolation of 1-D coordination polymer, YCM-42, containing the previously unreported [In(CO2R)2Cl2]− building unit. The 1-D herringbone structure of YCM-42 can be found in YCM-41. Finally, attempts to synthesize an isoreticular version of these structures led to the synthesis of the 1-D coordination polymer YCM-51, which contains a [I...
