| Outline of Final Research Achievements |
Two-dimensional multinuclear complexes are less common than other structurally regulated complexes such as one-dimensional complexes. Incorporation of electron-donating silylene and germylene ligands to the multimetallic complexes would confer unique chemical properties. This research reports modified preparation and chemical reactivity of tetranuclear palladium and platinum mixed complexes and their structural rearrangements of the Pd4Si3, PtPd3Si3, and Pd4Ge3 cores.
Preparation of the tetrapalladium complexes was modified by using silylene precursors, which was reported as aminosilylboronic ester. The direct reactions gave thermodynamically stable Pd4 complexes in good yields. The planar-shaped tetranuclear complexes with electron-donating silylene ligands exhibited unusual rearrangements of the cores by protonation. Especially, the protonation of the Pd4Ge3 core underwent reversible rearrangements to give the linear structure and the relative mechanism was also considered.
