摘要
The complexes cis/trans-[M{Ph(2)P(E)NHPPh(2)}(2)]Cl-2 and [M{Ph(2)P(E)NPPh(2)}(2)] (M = Pd or Pt) E = S or Se) have been prepared and characterised. The crystal structures of two representative examples trans-[Pt{Ph(2)P(Se)NHPPh(2)}(2)]Cl-2 and cis-[Pt{Ph(2)P(Se)NPPh(2)}(2)], have been determined. The PtSeP2N rings are puckered in both cases although there are some differences as a result of the formal charge upon the ligand and the cis/trans geometries. The cis neutral complex has shorter Pt-P and longer Pt-Se bonds than those of the trans protonated complex. Deprotonation of the ligand also results in a significant shortening of the P-N bond lengths.
