2-(3-Methoxy­salicylideneamino)-1H-benzimidazole monohydrate

The molecule of the title compound, C₁₅H₁₃O₂N₃·H₂O, is nearly planar, with an intramolecular N...O hydrogen bond of 2.616 (2) Å. It exists in the phenol–imine form and the dihedral angle between the two aromatic ring systems is 1.04 (5)°. An unsolvated form, crystallized from the same medium, has also been reported [Odabąsoglu, Albayrak & Büyükgüngör (2005). Acta Cryst. E61, o425–o426].

O,O-Bis(2-tert-butyl-4-methyl­phenyl) chloro­thio­phospho­nate

The title compound, C₂₂H₃₀ClO₂PS, displays distorted tetrahedral geometry around the P atom. The dihedral angle between the benzene rings is 43.7 (4)°. The aromatic rings have unusual endocyclic angles as a result of the steric effects of the tert-butyl groups. The mol­ecules are linked by weak C—H...π interactions.
