On December 14, 2017, Loubert, Gael; Volkringer, Christophe; Henry, Natacha; Arab-Chapelet, Benedicte; Delahaye, Thibaud; Loiseau, Thierry published an article.COA of Formula: C6H13NO The title of the article was Structural studies of a series of uranyl alkylacetamides and piracetam complexes obtained in nitric acid aqueous solution. And the article contained the following:
Three uranyl amide complexes have been isolated from slow evaporation technique from an aqueous solution of nitric acid (0.5 M), in the presence of N’,N-diethylacetamide (noted dam; compound 1), N-ethylacetamide (noted eam; compound 2) and 2-(2-oxopyrrolidino)acetamide (or piracetam, noted pam; compound 3). It results in the formation of crystalline mol. assemblies of UO2(L)2(NO3)2 neutral moieties (L = amide ligand), in which the uranyl center is coordinated to two chelating nitrate groups either in cis positions (1) or trans positions (2 and 3) and two organic ligands, through the amide functionality. The corresponding coordination geometry for uranyl is a hexagonal bipyramid, with the two typical trans U:O bondings. Single-crystal x-ray diffraction anal. revealed the bond lengths of U-Oamide are for 2.362(3), 2.363(3) and 2.374(2) Å for 1, 2 and 3, resp. The three complexes have been further characterized by IR spectroscopy and their thermal behavior has been evaluated by thermogravimetry. The experimental process involved the reaction of N,N-Diethylacetamide(cas: 685-91-6).COA of Formula: C6H13NO
