Dimeric associations (75) are typical of some low oxidation state and coordinatively unsaturated complexes that spontaneously exhibit a tendency to completely fill the valence electronic shell around the metal. Dinuclear dihydride [(C5H4Me)2ZrH(/x-H)]2, for which the two metallocene-H units are joined by two Zr-H-Zr (two-electron-three-center bonds) are examples of this family. ... [Pg.5305]

Similar structural characteristics of the quadruply bridged dinuclear complexes of Pt(II), Pd(II), and Ni(II) indicate that the mixed-metal dinuclear complexes of these metal ions should be stable. However, probably because of the synthetic difficulties, only a few mixed-metal complexes of group 10 elements with such a structure have been prepared so far, although there are a number of examples having a doubly bridged structure (98, 99). For other metals, quadruply bridged mixed-metal complexes are known with the group 6 metal ions Cr, Mo, and W (1, 100, 101). [Pg.214]

Ooi and co-workers adopted an elegant synthetic approach to the mixed-metal complexes of 4-methylpyridine-2-thiolate (4-mpyt). This approach includes the initial preparation of mononuclear complexes [M(4-mpytH)4]Cl2 (M = Pt, Pd), in which all four 4-mpytH ligands coordinate to with sulfur-donor atoms (84,102). The structure of the mononuclear Pd(II) complex with nonsubstituted pyridine-2-thiolate, [Pd(pytH)4]Cl2, is shown in Fig. 16 (84). These mononuclear complexes can be further reacted with the second metal ion to give mixed-metal dinuclear complexes. [Pg.214]

Reactions of alkynes with hydrosilanes under CO (1-30 atm) catalyzed by Rh4(CO),2 or Rh2Co2(CO),2 give /3-formylvinylsilanes in high to excellent yields . This reaction, silylformylation, is dso a silylcarbonylation, but it proceeds via a different mechanism from the Co2(CO)8-catalyzed silylcarbonylation. In fact, Co2(CO)g is inactive for silylformylation. The reaction catalyzed by Co2Rh2(CO),2 is proposed to involve the Co-Rh mixed metal dinuclear complexes as active catalyst species. ... [Pg.323]

Ni and Power describe the use of sterically demanding terphenyl ligands to synthesize transition metal dinuclear compounds of type ArMMAr that have exceptionally short M-M bonds and high M-M bond orders. For example, ArCrCrAr is described as possessing a quintuple Cr-Cr bond. [Pg.317]

Pomeroy et al. reported the only examples of Ru-Os mixed-metal dinuclear complexes in this review period, [cis-Ru(SiCl3)2(CO)4] reacted with [Os(PMe3)(CO)4] or [Os(CNBu )2(CO)3] to give [RuOs(PMe3)(SiCl3)2(CO)7] 52 or [RuOs(CNBu )2(SiCl3)2(CO)6] 53 (Table 4). ... [Pg.1055]
