ABSTRACT: The title compound, C(28)H(30)N(2)OS(2), was obtained by thio-nation of 3',6'-bis-(diethyl-amino)-3H-spiro-[isobenzofuran-1,9'-xan-thene]-3-one with 2,4-bis-(p-methoxy-phen-yl)-1,3-dithia-diphos-phetane disulfide (Lawesson's reagent). The planes of the two benzene rings of the xanthene system are inclined at a dihedral angle of 17.4 (1)°, and the plane of the dithio-phthalide group and the planes through the two benzene rings of the xanthene system make dihedral angles of 80.2 (1) and 82.8 (1)°, respectively.
