✦ Synopsis

The ligand 1,1%-bis(diphenyloxophosphoryl)ferrocene, dpopf, reacted with silver derivatives to afford mononuclear complexes, [Ag(OClO 3 )(dpopf)] (1), [Ag(dpopf) 2 ]ClO 4 , [Ag(dpopf)(PPh 3 )]ClO 4 , or the dinuclear complex, [{Ag(PPh 3 )} 2 (dpopf)](ClO 4 ) 2 . From 1, other three-, [Ag(dpopf)(SPPh 3 )]ClO 4 , and four-coordinated derivatives, [Ag(dpopf)(PPh 3 ) 2 ]ClO 4 (6) [Ag(dpopf)(L L)]ClO 4 [L L= bipy, (SPPh 2 ) 2 CH 2 ] were obtained by substitution reactions. The crystal structure of 6 was solved and revealed the expected distorted tetrahedral coordination at silver, with a ligand bite angle of 96.10(13)°.
