Abstract
The title compound, 2-tert-butyl-5(4-tert-butylbenzylthio)-4-chloropyridazin-3(2H-one, was synthesized from 1-tert-butylhydrazine, (Z)-2,3-dichloro-3-formylacrylic acid and (4-tert-butylphenyl) methanethiol in several steps. It crystallized in an orthorhombic space group Pnma with Mr = 364.93 (C19H25CIN2OS), a = 1.0091(2) nm, b = 0.7076(2) nm, c = 2.8103(5) nm, V = 2.0066(6) nm3, Z = 4, Dc = 1.192 g/cm3, F(000) = 765, μ = 0.301 mm-1, final R1 = 0.0665, and wR = 0.1913 for 1927 unique reflections. Inter- and intramolecular hydrogen bond C—H…O interactions stabilize the structure.
