Fifteen 4-(2-methoxyphenyl)piperazin-1-ium salts containing organic anions have been prepared and structurally characterized. In the isostructural 4-chlorobenzoate and 4-bromobenzoate salts, C11H17N20+·C7H4ClO2- (I) and C11H17N20+·C7H4BrO2- (II), and the 4-iodobenzoate salt C11H17N20+·C7H4IO2- (III), the ions are linked by N-H···O hydrogen bonds, forming centrosym. R44(12) four-ion aggregates; a similar aggregate is formed in the 2-chlorobenzoate salt (V), isomeric with (I). In the 2-fluorobenzoate salt C11H17N2O+·C7H4FO2- (IV), and the isomorphous pair of salts, the 2-bromobenzoate (VI), isomeric with (II) and 2-iodobenzoate (VII), isomeric with (III), N-H···O and C-H···π(arene) interactions link the components into three-dimensional arrays. Four-ion R44(12) aggregates are also found in the 2-methylbenzoate, 4-aminobenzoate and 4-nitrobenzoate salts, C11H17N2O+·C8H7O2- (VIII), C11H17N2O+·C7H6NO2- (IX) and C11H17N2O+·C7H4NO4- (X), but those in (IX) are linked into complex sheets by an addnl. N-H···O hydrogen bond. In the 3,5-dinitrobenzoate salt, C11H17N2O+·C7H3N2O6-·2H2O (XI), N-H···O and O-H···O hydrogen bonds link the components into a complex ribbon structure. In the picrate salt, C11H17N2O+·C6H2N3O7- (XII), the four-ion aggregates are linked into chains of rings by C-H···O hydrogen bonds. In the hydrogen maleate salt, C11H17N2O+·C4H3O4- (XIII), two- and three-center hydrogen bonds link the ions into a ribbon structure while both anions contain very short but asym. O-H···O hydrogen bonds, having O···O distances of 2.4447 (16) and 2.4707 (17) Å. O-H···O Hydrogen bonds link the anions in the hydrogen fumarate salt (XIV), isomeric with (XIII), into chains that are linked into sheets via N-H···O hydrogen bonds. In the hydrogen (2R,3R)-tartrate salt, C11H17N2O+·C4H5O6-·1.698H2O (XV), the anions are linked into sheets by O-H···O hydrogen bonds. Comparisons are made with the structures of some related compounds The experimental process involved the reaction of 4-Iodobenzoic acid(cas: 619-58-9Product Details of 619-58-9)
4-Iodobenzoic acid(cas: 619-58-9) belongs to organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. Product Details of 619-58-9 Alkyl iodides react at a faster rate than alkyl fluorides due to the weak C-I bond.
