| Outline of Final Research Achievements |
Protonation was studied for the tetrapalladium complexes and triplatinum complexes with bridging germylene ligands. The reaction is influenced by the protic acid used, and protonation by weak organic acid causes reversible protonation and deprotonation.
Use of trifluoroacetic acid as the proton source provided the complex having a hydride ligand for the tetrapalladium core, which is considered to be the important intermediate of the total reaction, which is accompanied by change of the molecular structure. Further reaction resulted in an octanuclear complex having two tetrapalladium cores with cleavage of an Pd-Si bond and bishosphine spacer betseen the Pd4 cores. Based on these results, the mechanism of the protonation and accompanying structural change is clarified.
