Аннотация
The title compound (C20H18FN3O2, Mr = 351.37) is prepared and its crystal structure is determined by single crystal X-ray diffraction. The crystal is tetragonal, the P-42(1)c space group with a = 11.0922(6), b = 11.0922(6), c = 28.6271(15) Å, V = 3522.2(3) Å3, Z = 8, dx =
= 1.325 g/cm3, F(000) = 1472, μ = 0.095 mm-1, MoKα radiation (λ = 0.71073), R = 0.0505, wR = 0.1090 for 2433 observed reflections with I > 2σ(I). The X-ray diffraction analysis reveals that all ring atoms in the benzo[4,5]furo[3,2-d]pyrimidinone moieties are almost coplanar.
