Logical methods for preparing small metal clusters with heteronuclear metal-metal bonds can be devised by appreciating the isolobal relationships that exist between certain metal ligand combinations and organic fragments. Thus the group W(CO) 2 (r|-C 5 H 5 ) has frontier orbitals of similar pattern to those of CH, while those of Rh(CO) (r|-C 5 Me 5 ) and CH 2 are also similar. This paper shows how such ideas have been employed to generate compounds with bonds between rhodium and other metals.

Gold Clusters

Alkanethiol protected gold clusters of 29 kDa were prepared and separated by column chromatography. Laser desorption mass spectra of these clusters have been investigated. In the gas phase, monolayer–monolayer interaction leads to clustering of the protected clusters. Role of different matrices and effect of alkanethiol chain length on this process have been investigated.

The interaction of silver ion with a range of mixed-donor macrocyclic ligands incorporating nitrogen, oxygen and/or sulfur donors has been investigated. Complementary calorimetric and n.m.r. studies in acetonitrile (and its deuterated derivative) were used to investigate the nature of the equilibria present as the metal/ ligand ratio was varied. In all systems the formation of a 1 : 1 species was observed, with a 1:2 (metal/ ligand ) species also being formed in the presence of excess ligand in the majority of cases. Enthalpies of formation for the various complexes have been determined. Stepwise stability constants for the respective [ AgL ]+ + L ↔ [AgL2]+ equilibria have been estimated from the calorimetric titration data, and the factors promoting the formation of the 1:2 species are discussed. The studies confirm the enhanced affinity of AgI for thioether donors over ether donors.
