Abstract
C23H26053 is obtained by irradiating a solution of 9-xanthenethione and bis(tert-butylthio)ethyne. The crystals are monoclinic, P21/n, with a = 14.890 (5), b = 9 . 2 9 6 ( 5 ) , c = 1 6 . 3 4 2 ( 1 1 ) A , f l = 1 0 1 . 1 4 ( 5 ) ° , Z = 4. The structure was determined from 3427 independent diffractometer intensities with I > 2.5tr(I) by the heavy-atom method and refined to R = 0.054. Bond lengths and angles in the planar thiete ring indicate appreciable strain; the xanthene system is slightly curved.
