Transition metals xxiii

Following the many recent developments in the chemistry of metal carbonyl clusters and other metal-metal bonded species, interest has developed in silicon-transition-metal clusters. These will be defined for the present purpose as compounds containing (1) at least one metal-metal bond and (2) at least one silicon atom directly linked to two or more metal atoms. Thus compounds such as Me3SiOs(CO)4Os(CO)4-SiMe3 and R3SiOCCo3(CO)9 are excluded examples of compounds that meet these criteria are shown in Table XXIII.
