Synthesis, Crystal, and Biological Activity of a Novel Carbene Silver(I) Complex with Imidazole Derivative

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)angstrom , beta = 93.910(4)A degrees, V = 1639(4)angstrom(3), Z = 4, D (x) = 1.771 g/cm(3), F (000) = 864, mu(MoK (alpha)) = 1.278 mm(-1). The final R-1 = 0.0711 and wR(2) = 0.1903 for reflections with I > 2 sigma(I). In addition, the preliminary biological test showed that the title compound had anti-fungus yeast activity.
