Face-bridging

A much more subtle case of stabilisation due to the presence of face-bridging ligands is found in the two tetrahedral clusters Co4Cp4(p3-H)4 (dec. ca. 300 °C)134> and Ni4Cp4(p3-H)3 (dec. ca. 320 °C)133h The structure of the last compound is shown in Fig. 2. [Pg.17]

The face-bridging carbonyls in Fe4(CO)4Cp4 are strongly basic and, with Lewis acids, form a number of (9-bonded adducts of the type Fe4(C0)4 Je(C0A)xCp4... [Pg.55]

Whereas edge- and face-bridging hydrogen atoms are associated mainly with metal-metal orbitals already present in the tetrahedral skeleton (see last section) and therefore have limited steric requirements, terminal hydrides occupy a full coordination position. It is not surprising then that the only examples of tetrahedral species with terminal hydrides contain 11 and 10 carbonyls, [Ir4(CO)nH] and [Ir4(CO)ioH2]2 . (The assignment for [Ir4(CO)nH] is based on the structure determination of the analogous [Ir4(CO)nBr] and on the similarity of the ir spectra of the two species (11).)... [Pg.10]
