Abstract

Complexes {[(Zn(Bbtm)(H₂O)₄](NO₃)₂}_n (I) and [Cu(Вbtm)(NO₃)₂]_n (II) are formed due to the reactions of solutions of zinc and copper(II) nitrates with the bis(1,1'-1,2,3-benzotriazolyl)methane ligand (Bbtm). Their crystal structures are determined by X-ray diffraction analysis (CIF files ССDС nos. 1963126 (I) and 1963127 (II)). Complex I is a linear metal-organic framework (1D-MOF) in which the octahedral coordination of the central atom is provided by four water molecules and two nitrogen atoms of two Bbtm molecules in the trans position. In the structure of complex II, the coordination sphere of copper contains two nitrogen atoms of the Вbtm ligands and four oxygen atoms of two nitrate anions, one of which is bridging like the Вbtm ligand. This makes it possible to describe the structure of complex II as 3D-MOF. The luminescence spectra are recorded for earlier undescribed compound I. The emission maximum is observed at 363 nm. Compound I is also tested as a catalyst for the cycloaddition of СО₂ to epoxides. The synthesized MOF efficiently catalyzes the cycloaddition reactions for both monosubstituted and disubstituted epoxides.

基于双（1-苯并三唑基）甲烷，锌和硝酸铜的线性金属有机骨架

摘要

络合物{[（Zn（Bbtm）（H ₂ O）₄ ]（NO ₃）₂）_n（I）和[Cu（Вbtm）（NO ₃）₂ ] _n（II）由于溶液的反应而形成。带有双（1,1'-1,2,3-苯并三唑基）甲烷配体（Bbtm）的硝酸锌和硝酸铜（II）。其晶体结构通过X射线衍射分析确定（CIF文件СD编号1963126（I）和1963127（II））。复杂的我是线性金属-有机骨架（1D-MOF），其中中心原子的八面体配位由反位的四个水分子和两个Bbtm分子的两个氮原子提供。在络合物II的结构中，铜的配位球包含两个btm配体的氮原子和四个硝酸根阴离子的四个氧原子，其中一个像btm配体一样桥接。这使得将复合物II的结构描述为3D-MOF成为可能。记录了先前未描述的化合物I的发光光谱。在363nm处观察到最大发射。化合物我还测试作为СО的环加成的催化剂₂环氧化物。合成的MOF有效地催化了单取代和双取代的环氧化物的环加成反应。
