Li, Ang; Forte, Jeremy; Li, Yanling; Journaux, Yves; Lisnard, Laurent published an article in 2021. The article was titled 《Synthesis, structure and magnetic properties of an oxamate-based 1D coordination polymer built on pentametallic links》, and you may find the article in Inorganica Chimica Acta.Recommanded Product: Ethyl oxalyl monochloride The information in the text is summarized as follows:
The solvothermal reaction of the hexadentate 2-(oxamato)benzoic acid ligand (oaba) with copper(II) and cobalt(II) ions has yielded the [Cu4Co3(oaba)4(OH)2(DMF)6]·2(DMF)·1H2O (1) 1D coordination polymer. The single-crystal x-ray diffraction study reveals the formation of a neutral chain built from pentametallic complexes where each multi-polydentate ligand bridges four metal centers. The atypical morphol. observed here for an oxamate-based 1D polymer arises from the use of a ligand bearing extra coordination sites. Magnetometry indicates strong dominating antiferromagnetic interactions within the polymer resulting in a non-zero ferrimagnetic state at low temperature The results came from multiple reactions, including the reaction of Ethyl oxalyl monochloride(cas: 4755-77-5Recommanded Product: Ethyl oxalyl monochloride)
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. Lacking the ability to form hydrogen bonds, acyl chlorides have lower boiling and melting points than similar carboxylic acids. For example, acetic acid boils at 118 °C, whereas acetyl chloride boils at 51 °C. Like most carbonyl compounds, infrared spectroscopy reveals a band near 1750 cm−1.Recommanded Product: Ethyl oxalyl monochloride
