Racemic potassium [2‐(diphenylphosphano)ferrocenyl]acetate reacts with the dinuclear palladium(II) methyl‐phosphane complexes [{Pd( μ ‐Cl)Me(PR 3 )} 2 ] ( 1 ; R = Me ( a ), 2‐furyl ( b ), and Ph ( c )) under formation of a dipalladium(II) complex with triply coordinated phosphanocarboxylate ligand: ( R p , S p )‐[ μ ‐1κ 2 P, O: ‐ 2κO′ ‐{2‐(diphenylphosphano)ferrocenyl}acetato][ μ ‐ 1κO′ :2κ 2 P, O{2‐(diphenylphosphano)ferrocenyl}acetato]bis{methylpalladium(II)} ( 2 ), exclusively as ( R p , S p ) diastereoizomer ( meso ‐form). The solid‐state structures of 1a and 2 have been determined by single‐crystal X‐ray diffraction.
