Heterobimetallic gold-palladium cluster complexes. X-ray crystal and molecular structures of [(CO)Pd(AuPPh3)8](NO3)2 and [(P(OCH3)3)Pd(AuPPh3)6(AuP(OCH3)3)2](NO3)2

The role of fast atom bombardment mass spectroscopy (FABMS) in cluster characterization

“…An analysis of the isotopic distribution pattern for the most abundant mass ion in 3006. 4 -as counterion 11 , and these results shows, once more, the reliability of this technique.…”

“…Research involving ligand stabilized metal clusters has increased considerably in the last two decades and great progress has been achieved in this field. These compounds have gained attention among chemists and physicists due to their fascinating geometries, unique fluxional behavior, catalytic potential and interesting chemical reactivity 6,10,11 . Originally the studies of metal clusters dealt primarily with their synthesis and structure determination.…”

“…Since then only some new and novel clusters of this type have been synthesized and well characterized 12 2+ by HPLC . The cluster was later prepared with better yield using palladium acetate as precursor 11 . Another faster synthesis of this cluster has been carried out with Pd(PPh 3 )Cl 2 and AuPPh 3 NO 3…”

Selective and High‐Yield Synthesis of Oblate Superatom [PdAu8(PPh3)8]2+

“…This core motif is similar to that of the previously reported [PdAu 8 (PPh 3 ) 8 ](NO 3 ) 2 . [34] The averageb ond lengths for AuÀAu, AuÀPd, and AuÀPb onds in [36] The remarkable improvement in the yield of [PdAu 8 (PPh 3 ) 8 ] 2 + is mainly ascribed to the simplification of the protocols and the kinetic control of the clusterf ormation step. In this work, the [PdAu 8 (PPh 3 ) 8 ]Cl 2 clusters were produced directly from AuCl(PPh 3 ).…”

[(Ph3PAu)6(dppeAu2)(AuCl)4Pd], an Icosahedral Au12 Cluster with a Central Pd Atom

“…Chem. 1994 [7] It is interesting to note that acetaldehyde, which might he expected to form the secondary carbocation adduct I1 directly, was observed not to add to C&+ with a measurable rate (k < I x lo-'* cm3molecule-' sC1) [8]. 181 S. Petrie, G. Javahery, H. Wincel, J. Wang, D. K. Bohme, Int.…”
