Preparation and structure of cobalt(II) complexes with 3,5-dimethylpyrazole was written by Safronova, L. A.;Komyagin, N. T.;Yanovskii, A. I.;Struchkov, Yu. T.;Shebaldova, A. D.. And the article was included in Koordinatsionnaya Khimiya in 1987.Reference of 934-48-5 This article mentions the following:
CoCl2 reacted with 3,5-dimethylpyrazolylcarbamide in iso-PrOH with heating to give CoL2Cl2 (L = 3,5-dimethylpyrazole). CoL2Cl2 is monoclinic, space group C2/c, with a 15.011(1), b 8.2732(6), c 24.053(2) 鑴? 灏?96.045(7)鎺? Z = 8, R = 0.041, Rw = 0.054. CoL2Cl2 has a distorted tetrahedral structure in which L is monodentate. CoL2Cl2 was also characterized by IR and 13C NMR spectra. In the experiment, the researchers used many compounds, for example, 3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5Reference of 934-48-5).
3,5-Dimethyl-1H-pyrazole-1-carboxamide (cas: 934-48-5) belongs to pyrazole derivatives. The 1H-pyrazole provides an excellent means by which to provide the requisite hydrogen bond acceptor閳ユ徆onor motifs, whether as a monocyclic ring or as a fused indazole ring. Pyrazole rings have been used as core components of several leading non-steroidal anti-inflammatory drugs (NSAIDs) and antihypertensive drugs. It has also been found to be useful as a bifunctional ligand for metal catalysis.Reference of 934-48-5
