Bis(3,5-dimeth­oxy­phen­yl)phosphinic acid

By Wei Cheng, Zhi-Qiang Feng and Jun-Mei Tang


In the crystal structure of the title compound, C16H19O6P, inter­molecular O—H⋯O inter­actions link the mol­ecules into chains parallel to the b axis. These chains are linked by C—H⋯π and π–π inter­actions [centroid–centroid distance = 3.7307 (29) Å] into a three-dimensional network. The dihedral angle between the benzene rings is 73.5 (1)°. The C and O atoms of all four methoxy groups lie very close to the mean planes of their attached rings; the C atoms are 0.055 (2)–0.1038 (1) Å out of the mean plane of the attached rings
