4,6-Bis(diphenyl-phosphan-yl)-2,8-di-methyl-phenoxathiin dichloro-methane monosolvate.

ABSTRACT: The title compound, C(38)H(30)OP(2)S·CH(2)Cl(2), belongs to the xanthene family of ligands containing S- and O-donor atoms in the central heterocylic ring. Positions 2 and 8 on the xanthene backbone are functionalized with methyl groups to allow for the selective functionalization of the backbone at positions 4 and 6 with diphenyl-phosphanyl units. The title compound shows a significant 'roof-like' bending along the axis of planarity involving the O- and S-donor atoms and the benzene rings, resulting in a dihedral angle between the mean planes of the benzene rings of 32.88 (13)°.
