The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: quinoliniumhydrogensulphate(SMILESS: [O-]S(=O)(O)=O.C12=CC=C[NH+]=C1C=CC=C2,cas:530-66-5) is researched.Recommanded Product: 580-34-7. The article 《The structural systematics of protonation of some important nitrogen-base ligands. III. Some (univalent) anion salts of some hindered unidentate nitrogen bases》 in relation to this compound, is published in Zeitschrift fuer Anorganische und Allgemeine Chemie. Let’s take a look at the latest research on this compound (cas:530-66-5).
Recent structural studies of salts of the 2,2,6,6-tetramethylpiperidinium cation [tmpH]+ (chloride, bromide; thiocyanate) present as interesting dimeric or polymeric associations linked by pairs of directional H-bonds from the cationic = NH+2 moieties to ‘two-coordinate’ anions. Present single crystal x-ray studies have characterized the iodide, perchlorate, nitrate and trifluoroacetate complexes, all, like those of the preceding studies, [tmpH]+X- (anhydrous). A variety of forms are found: the nitrate compound is dimeric [[tmpH](O·NO·O)2[Htmp]], the trifluoroacetate compound being similar in form while the iodide and perchlorate salts are mixtures of dimers (with the anions essentially single atom bridges) and single-stranded helical polymers, the stoichiometric ratio of these being 1:1 and 2:1 in terms of [tmpH]X formula units, resp. A study of 4-keto-2,2,6,6-tetramethylpiperidinium thiocyanate shows it to be a dimer [[OtmpH](SCNNSC)[HtmpO]], unlike its previously studied chloride analog which is a cyclic tetramer. A new P21/n phase of diisopropylammonium chloride, derivative of the previously described P212121 and P21 forms, is reported, together with descriptions of protonated salts of the other hindered unidentate bases 2,6-lutidine (as the chloride salt), quinoline (as the perchlorate, trifluoroacetate, hexachlorostannate and bisulfate salts) and 2-quinaldine (as the chloride (anhydrous and monohydrate) and hexachlorostannate salts), all displaying arrays derivative of ion-pair formation (extended by anion-anion H-bonds as well in the bisulfate salt) and, in the case of the aromatic bases, dominated by parallel stacking.
From this literature《The structural systematics of protonation of some important nitrogen-base ligands. III. Some (univalent) anion salts of some hindered unidentate nitrogen bases》,we know some information about this compound(530-66-5)COA of Formula: C9H9NO4S, but this is not all information, there are many literatures related to this compound(530-66-5).
