4,6-Bis(diphenyl­phosphan­yl)-2,8-di­methyl­phenoxathiin dichloro­methane monosolvate

The title compound, C₃₈H₃₀OP₂S·CH₂Cl₂, 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 diphenyl­phosphanyl 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)°.

1-[4-(1H-imidazol-1-yl)phen­yl]ethanone monohydrate

In the crystal structure of the title compound, C₁₁H₁₀N₂O·H₂O, the solvent water mol­ecule links the organic mol­ecules through O—H...O and O—H...N hydrogen bonds, forming chains that run diagonally across the bc face. These chains are connected to adjacent chains through weak C—H...O inter­actions, resulting in hydrogen-bonded sheets extending along the b and c axes. The sheets are connected along the a axis through π–π inter­actions, with centroid–centroid distances of 3.7571 (9) and 3.7231 (9) Å.
