Two novel heterometallic octahedral clusters [Rh(4)Pt(2)(CO)(11)(dppm)(2)](1) and [Ru(2)Rh(2)Pt(2)(CO)(12)(dppm)(2)](2) were synthesized by the reaction of [Rh(2)Pt(2)(CO)(6)(dppm)(2)] with [Rh(6)(CO)(14)(NCMe)(2)] and Ru(3)(CO)(12), respectively. Solid state structures of 1 and 2 have been established by a single crystal X-ray diffraction study. Two dppm ligands in 1 are bonded to one platinum and three rhodium atoms, which form an equatorial plane of the Rh(4)Pt(2) octahedron. Two rhodium and two platinum atoms bound to the diphosphine ligands in 2 are nonplanar to give an octahedral C2 symmetric Ru(2)Rh(2)Pt(2)(dppm)2 framework. The (31)P NMR investigation of and (1D, (31)P COSY, (31)P-[(103)Rh] HMQC) and simulation of 1D spectral patterns showed that in both clusters the structures of the M(6)(PP)(2) fragments found in the solid state are maintained in solution.

in niedervalenten ~bergangsmetallkomplexen reaktive Zentren zur Anlagerung von Metall-Ligand-Fragmenten sein konnen, hat sich ein neues Synthesegebiet entwickelt. Die Produkte kbnnen sowohl homo-als auch heteronucleare Metall-Metall-Bindungen enthalten. Mit briickenbildenden Kohlenstoffatomen entstehen Dimetallacyclopropan-oder -cyclopropen-Strukturen, deren organische Komponenten (Alkyliden-oder Alkylidingruppen) ein weitgenchertes Reaktionsverhalten zeigen. Das von Hofjimann et al. entwickelte isolobale Modell, das eine Beziehung zwischen den Grenzorbitalen organischer Gruppen und denen von Metall-Ligand-Fragmenten herstellt, ist zu einer erfolgversprechenden Leith i e fur prlparatives Arbeiten geworden.

Metal‐Carbon and Metal‐Metal Multiple Bonds as Ligands in Transition‐Metal Chemistry: The Isolobal Connection

A new domain for synthesis has developed following recognition that the metal-carbon and metal-metal multiple bonds present in certain low-valent transition-metal complexes are reactive centers for the attachment of metal-ligand fragments. The products contain metalmetal bonds which may be homo-or heteronuclear in nature. If bridging carbon atoms are present, leading to dimetallacyclopropane or -cyclopropene structures, the organic groups (alkylidene or alkylidyne) have an extensive chemistry. The isolobal connection, developed by Hoffmann et al., relating the frontier orbitals of organic groups with those of metal-ligand fragments, has been crucial in guiding the preparative work. Angew.
