“…Similar chemical shifts to those of Pd3 were found for very small palladium nanoparticles on alumina [53] and iron oxide, [54] for [Pd(NH 3 ) 4 Cl 2 ] nanowires, [55] nitrogen-containing conjugated polymer-palladium systems, [56] and an amino-functionalized MCM-41-supported Pd2 complex [57] and are attributed to Pd 2 + bound to different ligands (Cl, N, O).
