Abstract: The title compound, 2-tert-buty-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(C19H25ClN2OS), 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 CHO interactions stabilize the structure.
