Synthesis, crystal, and biological activity of a novel carbene silver(I) complex with imidazole derivative
文摘
Reaction of 2-(1-methyl-1,2-dihydroimidazol-3-yl)acetonitrile tetrafluoroborate with silver oxide in dichloromethane readily yields [Ag(DIM)2]BF4, where DIM is 2-(1-methyl-1, 2-dihydroimidazol-3-yl)acetonitrile, representing a carbene organic ligand. The title compound was characterized by elemental analysis, IR, MS and single crystal X-ray diffraction. The crystal is of monoclinic system, space group C2/c with a = 14.010(18), b = 8.303(11), c = 14.936(20) ?, β = 93.910(4)°, V = 1639(4) ?3, Z = 4, D x = 1.771 g/cm3, F (000) = 864, μ(MoK α) = 1.278 mm-. The final R 1 = 0.0711 and wR 2 = 0.1903 for reflections with I > 2σ(I). In addition, the preliminary biological test showed that the title compound had anti-fungus yeast activity.
