The title compound (E)-2-[(4-tert-butyl-5-(4-methoxybenzyl)thiazol-2-ylimino)me- thyl]phenol was synthesized by the reaction of 5-(4-methoxybenzyl)-4-tert- butylthiazol-2-amine with salicylaldehyde, and its crystal structure was determined by single-crystal X-ray diffraction. The crystal belongs to the monoclinic system, space group P21/c with a = 5.9362(8), b = 11.5070(15), c = 29.460(4) ?, β = 97.326(3)°, V = 1995.9(5) ?3, Z = 4, F(000) = 808, C22H24N2O2S, Mr = 380.49, Dc = 1.266 g/cm3, S = 1.031, μ = 0.181 mm-1, the final R = 0.0474 and wR = 0.1441 for 4327 observed reflections (I > 2((I)). Intramolecular O-H…N hydrogen bond is observed in the crystal. The preliminary bioassay showed that the title compound exhibits 95% inhibition rate against Rhizoctonia solani at the test concentration of 500 mg/L.
