The coordination of pyridylcarboxylate (isonicotinic acid, IN) with copper (II) fabricates a Cu(IN)-MOF. The characteristic properties of the Cu(IN)-MOF are obtained via different analysis techniques such as XRD, SEM, BET, ICP, TG, etc. The advantage of copper(II) coordinated with a bi-functional organic linker (IN), containing a pyridyl and carboxylate group, is demonstrated by the chemical properties of which the Cu(II)-based MOF exhibits excellent catalytic performance for the CO₂ carboxylation of terminal alkynes. No noble-metal, co-catalyst, or additives are required to execute the reaction. The effectiveness of the Cu(IN)-MOF was demonstrated with a variety of substrates (>11). Moreover, the Cu(IN)-MOF, as a heterogeneous catalyst, can be recycled at least 5 times retaining its excellent catalytic performance. Herein, we report the first copper (II) metal-organic framework (Cu(IN)-MOF) applied for the carboxylation of alkynes with CO₂ demonstrating several advantages such as stable catalyst, avoiding the use of an expensive noble-metal, straightforward synthesis.

吡啶基羧酸盐（异烟碱酸，IN）与铜（II）的配位可制得Cu（IN）-MOF。Cu（IN）-MOF的特性是通过XRD，SEM，BET，ICP，TG等不同的分析技术获得的。铜（II）的优势与双功能有机连接基（IN）协同作用，含有吡啶基和羧酸根基团的化合物的化学性质表明，基于Cu（II）的MOF对CO ₂表现出优异的催化性能末端炔的羧化。不需要贵金属，助催化剂或添加剂即可进行反应。Cu（IN）-MOF的有效性已在多种底物（> 11）上得到了证明。此外，作为非均相催化剂的Cu（IN）-MOF可以循环使用至少5次，同时保持其出色的催化性能。本文中，我们报道了第一个用于将炔烃与CO ₂进行羧化反应的铜（II）金属有机骨架（Cu（IN）-MOF），它具有多种优点，例如稳定的催化剂，避免了使用昂贵的贵金属，操作简便合成。
