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

The title compound, C₂₂H₃₀ClO₄PS, displays distorted tetra­hedral geometry around the P atom. The dihedral angle between the benzene rings is 41.2 (2)°. Because of the steric effects of the tert-but­yl groups, the aromatic rings have unusual endocyclic angles. The mol­ecules are linked by weak C—H...π inter­actions.
