The title compound has been synthesized by the addition reaction of N-(4-cyano- pyrazole-3-yl)-3,5-difluorophenyl-imine and diisopropyl phosphate. Its structure was confirmed by means of IR, 1H NMR and elemental analysis. The single-crystal structure of the title compound was determined by X-ray crystallography. The compound crystallizes in monoclinic, space group C2/c with a = 18.9959(14), b = 9.2212(7), c = 22.1108(16) , β = 90.1540(10)°, V = 3873.0(5) 3, Dc = 1.366 g/cm3, Z = 8, μ = 0.185, F(000) = 1664, and the final R = 0.0503 and wR = 0.1539 for 2996 observed reflections (I > 2σ(I)). The results demonstrate that the dihedral angle between the pyrazole and benzene rings is 105.5°, and there is a full delocalized pyrazole system with sp2 hydridization of N(3). The crystal structure is stabilized by two intermolecular hydrogen bonds of N(1)-H(1)…O(3) and N(3)-H(3A)…N(4). The preliminary biological test shows that the title compound has a moderate antifungal activity.
