Crystal structure of zwitterionic 2-[bis­(2-meth­oxy­phen­yl)phosphanium­yl]-4-methyl­benzene­sulfonate monohydrate di­chloro­methane monosolvate

In the title compound, C(21)H(21)O(5)PS·H(2)O·CH(2)Cl(2), the phospho­nium–sulfonate zwitterion has the acidic H atom located on the P atom rather than the sulfonate group. The S—O bond lengths [1.4453 (15)–1.4521 (14) Å] are essentially equal. In the crystal, the water mol­ecules bridge two zwitter...

Descripción
Sumario:In the title compound, C(21)H(21)O(5)PS·H(2)O·CH(2)Cl(2), the phospho­nium–sulfonate zwitterion has the acidic H atom located on the P atom rather than the sulfonate group. The S—O bond lengths [1.4453 (15)–1.4521 (14) Å] are essentially equal. In the crystal, the water mol­ecules bridge two zwitterions via O(water)—H⋯O(sulfonate) hydrogen bonds into a centrosymmetric dimer. The dimers are further linked by weak C(Ar­yl)—H⋯O(sulfonate) hydrogen bonds into chains extending along [100]. The PH(+) group is not involved in inter­molecular inter­actions.
