Source of material
The 4-(dimethylamino)-1-(prop-2-yn-1-yl)pyridin-1-ium iodide (1 eq) was dissolved in dichloromethane to obtain a clear solution. To this solution was added a solution of potassium perchlorate (1.2 eq), followed by stirring under reflux for 3 h. The cooled reaction mixture was filtered through Celite to remove solid metal halide. The evaporation of dichloromethane led quantitatively to the desired 4-(dimethylamino)-1-(prop-2-yn-1-yl)pyridin-1 − ium perchlorate (C10H13N2)[ClO4]. Single crystals were obtained from a mixture of dichloromethane and n-hexane (1:2).
Experimental details
Hydrogen atoms were placed at the calculated positions and refined using a riding model with Uiso(H) = 1.2 Ueq or 1.5 Ueq of the adjacent non-hydrogen atom. The H9 atom (propynyl group) position was localized from the difference map and refined with DFIX 0.87 and Uiso(H) = 1.5 Ueq(O3) [1], [2]. The perchlorate anion shows a disorder (not shown in the figure).
Comment
Pyrimidine salt and its derivatives are pharmaceutically essential since they occur in nucleic acid system, therefore many pyrimidine-derivatives salts can served as drugs [3]. Given the importance of pyrimidine derivatives in some bio-systems, a lot of interest has been concentrated on such stable salt recently [4]. Because of the basic nitrogen-atoms in the backbone of pyrimidine derivatives it was used as proton-receptor or ligand [5]. Perchlorate anions are used as ligands for the elaboration of metal complexes having interesting applications in various fields [5], [6], [7], [8], [9]. Several organic cations can be used for the stabilization of these anions especially benzylammonium and pyrimidinium derivatives [9], [10], [11].
In the cation of the title salt the pyridinium ring and dimethyl amine group is approximately co planar, which may be supported by lone pair of N (NMe2). The propyne group is in semi-perpendicular plane to the pyridinium rings with 112° angle value. Moreover the propynyl is in the opposite direction of the perchlorate anion in order to minimize the repulsion.
