The cocrystal rac-1-[(N,4-di­methyl­benzene­sulfonamido)­methyl]-2-(di­phenyl­phosphoryl)­ferrocene-rac-1-[(N,4-di­methyl­benzene­sulfonamido)­methyl]-2-(di­phenyl­phosphanyl)­ferrocene (0.45/0.55)

Synopsis: Partial oxidation of a di­phenyl­phosphanyl group to a di­phenyl­phosphoryl group leads to a 0.55:0.45 cocrystal. The P=O distance [1.344 (4) Å] is the shortest observed for (di­phenyl­phosphoryl)­ferrocene compounds.

Formula: [Fe(C5H5)(C26H25NO2PS)]0.55·[Fe(C5H5)(C26H25NO3PS)]0.45
