Source of material
The title compound was synthesized by the reaction of 2-(2-amino-ethoxy)-ethanamine (0.29 mL, 2 mmol), formalin (0.58 mL, 6 mmol) and picolinaldehyde (0.38 mL, 4 mmol) in ethanol [4]. Hydrogen bromide (2 equiv) was added to the reaction mixture, which was stirred at room temperature for 12 h. Following salt metathesis with NH4PF6 in acetonitrile, a yellow solid was obtained, 0.98 g. Yield: 82%. 1H NMR (400 MHz, DMSO) δ [ppm] 9.62 (s, 2H), 8.54 − 8.45 (m, 2H), 8.13 (s, 2H), 7.75 (d, J = 9.3 Hz, 2H), 7.28 − 7.11 (m, 4H), 4.67 (t, J = 4.8 Hz, 4H), 3.90 (t, J = 4.8 Hz, 4H). 13C NMR (100 MHz, DMSO) δ [ppm] 129.40, 127.09, 125.04, 124.47, 118.49, 117.92, 114.05, 68.55, 50.36.
Experimental details
The structure was solved by Direct Methods. The largest residual density peaks are near the PF6 anions indicating a small additional disorder of these ions.
Comment
Despite a massive number of NHCs were reported using a variety of synthetic methods [5], [6], it remains a challenge to get NHCs with tunable electronic and steric properties. Many NHCs containing the imidazo[1,5-a]pyridine have been synthesized [7], [8], [9], [10], [11].
Geometric parameters in the title molecule are in the expected ranges. In detail the bond lengths of O1-C9 and O1-C10 are 1.419(6) and 1.409(6) Å, respectively, and the angle of C9-O1-C10 is 110.8(4)°. The supramolecular assembly in title compound depends on the combination of C-H⋯F hydrogen-bonding and π-π stacking. The imidazolium cation and hexafluoro phosphate anions are connected by C-H⋯F hydrogen-bond (d(H acceptor) and d(donor⋯ acceptor), donor-H⋯ acceptor): C12-H12A⋯ F6i (2.35, 3.207(8) Å), 153.0°; C13-H13A⋯ F11ii (2.55, 3.473(8) Å), 173.8°; C18-H18A⋯ F12iii (2.42, 3.232(9) Å), 146.4°. Symmetry codes: i = −x + 1, −y + 1, −z; ii = x, 1 + y, z; iii = −x, 1 − y, −z. In the π-π stacking, the aromatic rings of the molecules, which are strictly parallel, have an inter-planar spacing of 3.603(2) and 3.599(2) Å, respectively.
