Isocyanide bridging

In another type of isocyanide bridge-bonding mode X2-ti t1 (D in Figure 13.1), one metal binds to only the carbon while the second metal is formally 7t-bonded... 

Representative new types of bonding modes that have been observed are as follows with the isocyanide symmetrically bridging three cobalt atoms through the isocyanide carbon (1) (59) with the isocyanide bridging two... 

Os6(CO)l8(CNC6H4Me-p)2 (62) have shown the former to have the same Os6 bicapped tetrahedron of the parent compound Os6(CO) g, whereas the latter has a rearranged metal skeleton with one isocyanide bridging three osmium atoms (40). With the ruthenium product Rus(CO),4(CNBu )2 (63), isolated... 

Finally, there is a single example of an isocyanide-bridged bimetallic complex, viz. the metal—metal bonded [TpPd(p-CNXyl)]2 (510, Figure 5), prepared from [Pd2Cl2(CNXyl)4] and NaTp, alongside a variety of...

Not only does the incorporation of the dpm ligand into 1 inhibit dissociation, it also prohibits further Rh-Rh bond formation. The cations (RNC)i Rh+ can further associate to formtrimers via reaction (2). Additionally the isocyanide bridge complex 2 also self associates via reaction (3) to form a tetrarhodium species. However the dpm-bridged dimers, 1, show no evidence for self association even at the highest concentrations. Undoubtedly... 

The great majority of platinum(I) complexes are binuclear with monofunctional or bifunctional bridging groups. However, there is also a series of unsupported dimers with the general structure shown in (12). These are generally stabilized by phosphine, carbonyl, and isocyanide ligands.17 Dimeric hydride complexes can have terminal or bridging hydrides and these are discussed above in Section 6.5.2.1.4.
