. Can. J. Chem. 70, 792 (1992). The structures of three tetramethylammonium salts containing anions of formula [ ( p~e~h ) ( , (~~e~h ) , 1 ' -(M = Zn and Cd) were determined by single crystal X-ray diffraction techniques. The Zn salt crystallizes in different space groups depending upon the solvent combination used in the synthesis. Thus crystals of (MelN), [Zn,(SePh),o], 1, grown from a mixture of methanol, acetopitrile, and acetone are triclinic, space group P 1, with cell dimensions cz = 13.214 (2)

Professor Hans Bock zum 60. Geburtstag gewidmetMetallclustern wird in der Chemie und der Physik zunehmend Beachtung geschenkt, vor allem wegen der uberraschenden Resultate, die in vielen Fallen rnit der Synthese und Strukturaufklarung sowie dem Studium der physikalischen und chemischen Eigenschaften dieser Verbindungen einhergehen. Wahrend Untersuchungen der Reaktivitat von Metallclustern gegenwartig im wesentlichen auf drei-und vierkernige Cluster beschrankt sind, konnten in jungster Zeit auch Synthesen fur Cluster rnit sehr vielen Metallatomen entwickelt werden. Mit diesen Substanzen lassen sich moglicherweise Briicken zwischen der Festkorperchemie und der Komplexchemie schlagen. In dieser Ubersicht wird ein vielseitig anwendbares und ausbaufahiges Verfahren zur Synthese von Metallclustern beschrieben. Dazu werden Ubergangsmetallhalogenid-Komplexe rnit silylierten Verbindungen wie E(SiMe3)2 (E = S, Se, Te) und E'R(SiMe3)2 (R = Ph, Me, Et; E' = P, As, Sb) umgesetzt. Diese Methode bietet einen einfachen Zugang zu nieder-und hochmolekularen Ubergangsmetallclustern rnit ungewohnlichen Strukturen und Valenzelektronenkonzentrationen sowie vielfaltigen Reaktionsmoglichkeiten in der Ligandensphare.

Dedicated to Professor Hans Bock on the occasion of his 60th birthdayIn both physics and chemistry, increased attention is being paid to metal clusters. One reason for this attitude is furnished by the surprising results that have been obtained from studies of the preparation, structural characterization and physical and chemical properties of the clusters. Whereas investigations of cluster reactivity are at present generally limited to three-or four-membered clusters, successful syntheses of clusters with many more metal atoms have recently been designed. These substances occupy an intermediate position between solid state chemistry and the chemistry of metal complexes. This review presents a versatile method for synthesizing metal clusters: the reaction of complexes of transition metal halides with silylated compounds such as E(SiMe,)' (E = S, Se, Te) and E'R(SiMe3)2 (R = Ph, Me, Et; E' = P, As, Sb). Although some of the compounds thus formed have already been prepared by other routes, the method affords ready access to both small and large transition metal clusters with unusual structures and valence electron concentrations: a variety of reactions in the ligand sphere are also possible.
