A planar tetranuclear palladium cluster was obtained from the reaction of a cyclotetrasilane with [Pd(CN t Bu) 2 ] 3 . Single‐crystal X‐ray diffraction analysis and DFT calculations revealed that the tetranuclear framework of the cluster was supported effectively by the bridging organosilylene ligand. Although [Pd(CN t Bu) 2 ] 3 as well as mononuclear palladium bis(silyl) complex, cis ‐Pd(SiMePh 2 ) 2 (CN t Bu) 2 , do not act as the effective catalyst, the planar tetranuclear palladium cluster acts as an efficient catalyst for the hydrogenation of alkenes and alkynes including sterically hindered tri‐ and tetra‐substituted alkenes.
