The title compound (C19H27BF2N2, M, = 332.24) was obtained by the reaction of 2,4-dimethyl-3-ethylpyrrole with triethylamine and boron trifluoride diethyl etherate in dichloroethane. Its structure was characterized by elemental analysis, IR,H-1 NMR, MS and X-ray diffraction. The crystal of title compound belongs to triclinic system with space group P-1(-) (No. 2) and cell parameters: a = 1.225 7(2), b = 1.783 0(8), c = 0.887 7(2) nm, alpha = 100.26 (2), beta = 107.57 (1), gamma = 76.96 (2)degrees, V = 1.789 2 (9) nm(3), M, = 332.24, Z = 4, D-c = 1. 233 g.cm(-3), mu (MoKalpha) = 0. 86 cm(-1), F (000) = 712. 00. R = 0. 051, R-omega = 0.060. In the molecule, all non-H atoms except C(12), C(15), C(18), F(I), F(2) are on the same plane. Based on its crystal data, we have also discussed the relationship between structure and property of title compound.
