Treatment of dicobalt octarbonyl with a 2 1 mixture of t-butylacety-lene and acetylene forms a remarkable cobalt complex of stoicheimometry Co2(CO)4(C2HBu )2(C2H2). The structure of this compound, 9.7, provides a fascinating insight into a mechanism of polymerization of acetylenes. The bonding of the hydrocarbon residue in complex, 9.7, may be described in terms of a fly-over , bis-enyl system. The distance Co—C3 (fl enyl) is 2-04 A. [Pg.232]

The complex gives ortAo-di-/-butyl benzenes on decomposition by bromine. The formation of the ortho substituted t-butyl benzenes which cannot be prepared by direct substitution of benzene, can be und tood in the light of the structure of the cobalt complex, 9.7, since the carbons attached to the r-butyl groups occupy adjacent positions in the complex. [Pg.232]

The above examples should illustrate the great variety of metal complexes and organic compounds which result from the reaction of acetylenes with compoimds of the transition metals. It can be anticipated that reactions of this kind will become increasingly important as synthetic routes to organic compounds which are not otherwise so readily obtained. [Pg.232]

H2 or O2 from water in the presence of a sacrificial reductant or oxidant employ a mthenium complex, typically [Ru(bipy)2], as the photon absorber (96,97). A series of mixed binuclear mthenium complexes having a variety of bridging ligands have been the subject of numerous studies into the nature of bimolecular electron-transfer reactions and have been extensively reviewed (99—102). The first example of this system, reported in 1969 (103), is the Creutz-Taube complex [35599-57-6] [Ru2(pyz)(NH3. [Pg.178]

Numerous tetrahedral halogeno complexes [T1" X4] (X = Cl, Br, I) have been prepared by reaction of quaternary ammonium or arsonium halides on TIX3 in nonaqueous solution, and octahedral complexes TI "X< ] (X = Cl, Br) are also well established. The binuclear complex Cs3[Tl2"Cl<)J is an important structural type which features two TlCls octahedra sharing a common face of 3 bridging Cl atoms (Fig. 7.9) the same binuclear complex structure is retained when Tl " is replaced by Ti ", V ", Cr " and Fe " and also in K3W2CIS and CssBiily, etc. [Pg.240]

The binuclear complex [Mo2Cl2N2o] features a terminal nitrido ligand, N=, as well as terminal and bridging azido ligands, i.e. [ (MoCl(N)(t, -N,)2(/t,t -Nt)l2] Concatenations larger than N3 are rare. The planar bridging N4... [Pg.419]
