A series of ionic uranyl-containing complexes, namely [C2mim]2[UO2(ccnm)4] (1), [C4mim]2[UO2(ccnm)4] (2), [N1111]2[UO2(ccnm)4][H2O]2 (3), and [P2444]2[UO2(dcnm)2(ccnm)2] (4) (ccnm)– = carbamoylcyanonitrosomethanide; dcnm = dicyanonitrosomethanide; (C2mim)+ = 1-ethyl-3-methylimidazolium; (C4mim)+ = 1-butyl-3-methylimidazolium; (N1111)+ = tetramethylammonium; (P2444)+ = tributyl(ethyl)phosphonium were isolated from in situ formed dcnm-based ionic liquids and characterized systematically. It was found that the dcnm anions transformed into ccnm anions during the reactions. These anions coordinate with the uranyl cations in chelate or terminal monodentate coordination mode, affording neg. divalent complex anions which can combine with different organic cations and form ionic uranyl-containing complexes. Plenty of C-H···O, N-H···O, C-H···N, N-H···N, and H···H weak interactions are formed in the crystal structures. The transformation of cyano to amide groups contributes to the crystallinity and leads to higher m.ps. as well as the luminescence quenching of these compounds The speciation of uranyl-containing ionic complexes in in situ formed dicyanonitrosomethanide-based ionic liquids was investigated. Four ionic uranyl-containing complexes with varying organic cations and complex anions were successfully obtained by competing coordination and metathesis reactions. Some of the cyano groups in the ligands hydrolyzed to amide groups, contributing to the formation of many weak interactions and crystallization The thermal stability, phase transition behaviors, and photophys. properties were also investigated. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0HPLC of Formula: 75-57-0).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.HPLC of Formula: 75-57-0
