4-(2-Chlorophenyl)-3-(2,6-dichlorophenyl)spiroisoxazoline-5,2′-benzo[4,5]imidazo[2,1-b]thiazol-3′-one dioxane hemisolvate

Abstract

The title compound, C23H12Cl3N3O2S·0.5C4H8O2, was synthesized by the intermolecular [3+2]-cyclo­addition of 2,6-di­chloro­benzo­nitrile oxide and 2-(2-chloro­benzyl­idene)­benzo­[4,5]­imidazo­[2,1-b]­thia­zol-3-one. The dioxane mol­ecule of solvation is located about a centre of inversion. A spiro junction links an isoxazoline ring and a planar benzo­[4,5]­imidazo­[2,1-b]­thia­zol-3-one ring.
