(6,6′-Dimeth­oxy­biphenyl-2,2′-di­yl)bis(diphenyl­phosphane) P,P′-dioxide dihydrate

In the title compound, C₃₈H₃₂O₄P₂·2H₂O, the dihedral angle between the meth­oxy­phenol rings is 84.11 (7)°. O—H...O hydrogen bonds connect the water mol­ecules of crystallization with the main mol­ecule.

2-(Ethyl­sulfin­yl)imidazo[1,2-a]pyridine-3-sulfonamide

The supra­molecular structure of the title compound, C₉H₁₁N₃O₃S₂, is defined by two inter­molecular hydrogen bonds. Pairs of N—H...N hydrogen bonds link the mol­ecules into centrosymmetric dimers and N—H...O hydrogen bonds link the dimers into a tubular chain structure running parallel to the a axis.
