Triphenylphosphine–amino acid bioconjugates Ph 2 P‐ p C 6 H 4 ‐Aa‐OR [Lig; Aa = glycine ( 1G ), alanine ( 2A ), valine ( 3V ), isoleucine ( 4I ), proline ( 5P ), or phenylalanine ( 6F )] were synthesized and used as monodentate ligands for the preparation of twelve metal complexes, [MCl 2 (Lig) 2 ] (M = Pd II or Pt II ). All of the prepared compounds were characterized by spectroscopic methods, and the structures of ligand 1G and complexes 1G Pd , 4I Pd , and 6F Pd were determined by X‐ray single‐crystal diffraction. The cis and trans configurations of the square‐planar metal complexes were investigated by solution NMR spectroscopy and computational methods.
