Synthesis and crystallization of 3-methyl-1-propyl-1,3-dihydro-1H-imidazol-2-ylidene)silver(I) chlorido(5,10,15,20-tetraphenylporphinato)cadmate(II) was written by Bruekers, J. P. J.;Elemans, J. A. A. W.;Nolte, R. J. M.;Tinnemans, P.. And the article was included in IUCrData in 2022.SDS of cas: 79917-89-8 This article mentions the following:
The structure of the title salt, [Ag(C7H12N2)2][CdCl(C44H28N4)], at 150 K has triclinic symmetry. One of the Ph rings bonded to the porphyrin mol. and the Pr groups of both ylidene mols. coordinating to silver are disordered over two positions. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8SDS of cas: 79917-89-8).
1-Methyl-3-propylimidazolium Chloride (cas: 79917-89-8) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole is incorporated into many important biological compounds. The most pervasive is the amino acid histidine, which has an imidazole side-chain. Histidine is present in many proteins and enzymes, e.g. by binding metal cofactors, as seen in hemoglobin.SDS of cas: 79917-89-8
