Platinum(II) complexes containing hydrazide‐based aminophosphine ligands: Synthesis, molecular structures, computational investigation and evaluation as antitumour agents

Four new N , N ‐bis(diphenylphosphino)amine ligands (where amine = 1‐amino‐4‐methylpiperazine (L 1 ), N ‐aminophthalimide (L 2 ), 4‐aminomorpholine (L 3 ) and hydrazine dihydrochloride (L 4 )) and their Pt(II) complexes C 1 , C 2 , C 3 and C 4 were synthesized and characterized using infrared and NMR spectroscopies. The crystal structures of C 1 , C 2 and C 3 were determined using single‐crystal X‐ray diffraction techniques. The antitumour...
