Synthesis, Crystal Structure, and Fungicidal Activity of 5‐(4‐cyclopropyl‐5‐((3‐fluorobenzyl)thio)‐4H‐1,2,4‐triazol‐3‐yl)‐4‐methyl‐1,2,3‐thiadiazole

A new 1,2,3-thiadiazole compound was synthesized and characterized. The crystal structure of the title compound (C15H14FN5S2, Mr = 347.43) has been determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P-1 with a=7.0490(14), b=9.0212(18), c=12.799(3) Å, α = 89.97(3)°, β = 82.27(3)°, γ = 73.17(3)°, V = 771.3(3)  Å3, Z = 2, F(000) = 360, Dc = 1.496 g/cm3, μ = 0.036 mm−1, the final R1 = 0.0358, and wR2 = 0.0986 for 2204 observed reflections with I>2σ(I). A total of 5697 reflections were collected, of which 2719 were independent (Rint=0.0028). The herbicidal activity of title compound was determined; the results showed that the title compound displayed excellent fungicidal activity
