DOIAbstract
(dippe)Pd(C2H4) and (dtbpe)Pd(C2H4) react with an excess of CO to afford the novel tetrahedral Pd0−dicarbonyl complexes (dippe)Pd(CO)2 (1) and (dtbpe)Pd(CO)2 (2). Partial CO elimination from 2 yields dinuclear {(dtbpe)Pd}2(μ-CO) (3), containing a single bridging carbonyl ligand. 3 represents the smallest cluster containing the Pd2(μ-CO) group and, as such, is also the simplest model compound for CO adsorption on a Pd(100) surface. Thermolysis of 3 produces a carbonyl-free product which is assumed to be the dinuclear species {(dtbpe)Pd}2 (4). The molecular structures of 2 and 3 have been determined, and the solids are furthermore characterized by CP-MAS NMR spectra
