“…herald to the first genuine triple-decker complex, the cationic [Ni2(C 5H5)3 ] ÷ moiety (Werner & Salzer, 1972;Salzer & Werner, 1972a). Since then some carboraneand thiocarborane-containing triple-decker complexes with fillings of Co and Fe respectively have been structurally characterized (Beer, Miller, Sneddon, Grimes, Mathew & Palenik, 1973;Pipal & Grimes, 1978;Siebert, Renk, Kinberger, Bochmann & Krfiger, 1976).…”

“…In particular, the metalligand sandwich systems have attracted the attention of scientists for more than a half century following the discovery of ferrocene, Fe(η 5 -C 5 H 5 ) 2 . 53,54,59 Although a few examples of the synthesis of triple-decker sandwich complexes composed of transition-metal atoms and cyclopentadienyl (C 5 H 5 ; Cp) ligands such as Ni 2 Cp 3 + (in the bulk) 60 and Fe 2 Cp 3 + (in the gas phase) 61 have been reported, these complexes have attracted much attention for the detailed study of metalligand interactions in organometallic systems.…”

“…The development of a vaporization target widened the combination of the elements for the composite clusters. Indeed, the laser vaporization is applicable to the soft solid of alkaline metal elements such as lithium (Li) and sodium (Na) 18b and also to the powder C 60 by molding them as a rod shape, where the C 60 rod has been prepared by pressing purchased C 60 powder. 24a In this work, the cluster source was modified so that the composite clusters could be more effectively generated.…”

Clusters consisting of 101000 atoms size-dependently exhibit novel electronic and geometric properties. In particular, composite clusters composed of several elements and/or components provide a promising way for a bottom-up approach for designing functional advanced materials, because the functionality of the composite clusters can be optimized not only by the cluster size but also by their compositions. This account surveys recent investigations of composite clusters focusing on the efforts to create a new functional composite cluster by a fine doping or hybridization based on their size-specific electronic properties. Organometallic clusters and caged clusters are demonstrated as a representative example of designing the functionality of magnetism and electronic state structures. In order to create functional nanomaterials, furthermore, a fine controlling methodology of the soft-landing technique has been developed to fix the composite clusters onto a surface decorated with a self-assembled monolayer. The embedded isolation mechanism on the substrate is discussed form the viewpoint of self-assembly phenomena with the molecular ordering of ·· interaction, and also the electronic structures characterized by molecular ordering of ³³ interaction is intrinsically revealed by molecular clusters of ³-conjugate polyacenes as a model for self-assembled aggregates.

“…3-5 The cationic species [CpM] + also proved to be useful in the chemistry of metallacarboranes. For example, these species were used for the synthesis of complexes with the tricarbollide [C 3 2+ . The formation of the latter complex is apparently associated with low stability of the corresponding triple decker RhIr structure due to its low symmetry.…”

Our recent studies on the synthesis of metallacarboranes based on the cationic species [(Carb)M] + are summarized. The labile complexes [Carb´M(Solv) 3 ] 2+ (Carb´ = 9 SMe 2 7,8 C 2 B 9 H 10 ; M = Rh or Ir) and [Carb´Fe(C 6 H 6 )] + were suggested to use as synthons. The new method was employed to synthesize a great variety of sandwich, half sandwich, and triple decker complexes.The species [CpM] + are widely used in organometallic synthesis. In particular, these species react with Cp -and C 6 H 6 to form metallocenes MCp 2 and arene complexes [CpM(C 6 H 6 )] + , respectively. 1,2 The analogous reactions with MCp 2 produce triple decker complexes. 3-5 The cationic species [CpM] + also proved to be useful in the chemistry of metallacarboranes. For example, these species were used for the synthesis of complexes with the tricarbollide [C 3 B 8 H 11 ] -(see Ref. 6), phosphadicarbollide [PC 2 B 8 H 10 ] -, 7 and dicarbollide [9 SMe 2 7,8 C 2 B 9 H 10 ] -(see Ref. 8) anions. Due to the single negative charge, these anions are close analogs of Cp -in the ability to be coordinated to transition metals. This suggests the simi larity of the cationic species [CarbM] + and [CpM] + . The present review summarizes our recent results on the generation of the metallacarborane species [Carb´M] 2+ (Carb´ = 9 SMe 2 7,8 C 2 B 9 H 10 ; M = Rh or Ir) and [Carb´Fe] + and their use in organometallic synthesis. Rhodium and iridium complexes. The rhodium and iridium cyclopentadienyl chloride complexes [Cp*MCl 2 ] 2 are widely used as synthons of the cationic species [Cp*M] 2+ for the synthesis of arene, 9-11 triple decker, 5,12-14 Scheme 1 M = Rh, Ir; X = Cl, Br, I; Solv = Me 2 CO, MeNO 2 Scheme 2 R = H, Me
