In 2019,Crystal Growth & Design included an article by Kalinke, Lucas H. G.; Cangussu, Danielle; Lloret, Francesc; Bruno, Rosaria; Armentano, Donatella; Pardo, Emilio; Ferrando-Soria, Jesus. Formula: C4H5ClO3. The article was titled 《A Metalloligand Approach for the Self-Assembly of a Magnetic Two-Dimensional Grid-of-Grids》. The information in the text is summarized as follows:
The efficient organization of discrete functional mols. into extended frameworks, while retaining their phys. properties, is a mandatory requisite to move toward applications. Here the authors describe the validity of the metalloligand design strategy as a versatile and powerful approach to build up a two-dimensional (2D) magnetic metal-organic framework (MOF) composed of preformed discrete antiferromagnetically coupled [3 × 3] CuII9 incomplete grids. In the 1st stage, a novel oxamato-based nonanuclear copper(II) complex was self-assembled from the reaction of a polytopic organic ligand, with well-defined coordination pockets, with CuII ions. Then, the nonanuclear complex was used as metalloligand toward calcium(II) cations to afford a CaII-CuII 2-dimensional MOF [Ca3(H2O)12[Cu9(dabtzox)6μ2(H2O)4μ3(H2O)2]].20H2O (1) with a grid-like topol. and the magnetic properties of the preformed nonanuclear grids. In the experimental materials used by the author, we found Ethyl oxalyl monochloride(cas: 4755-77-5Formula: C4H5ClO3)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Formula: C4H5ClO3
