Metal carbonyl complexes, solid state

Carbonylation reactions with microwave irradiation have been investigated in connection with solid-state combinatorial chemistry.Since reactions requiring gaseous reagents cannot use microwave irradiation, metal carbonyl complexes, such as Mo(CO)6, Cr(CO)6, W(CO)6, and Co2(CO)8 have been employed as source of carbon monoxide. " Examples of aminocarbonylation performed with microwave irradiation are presented in Section 11.15.4.3 (vide supra). 

Solid State NMR Investigations of Metal Carbonyl Complexes... 

In recent years there has been considerable interest in the application of solid state NMR techniques to obtain structural and dynamic information on a wide variety of metal carbonyl complexes since solid state NMR can act as a bridge between crystallographic information and structures in solution. The NMR spectra of solids are, in principle, more complex than those in solution state because molecular motions in the latter case cause averaging of many interactions which are orientation dependent. This motional averaging brings several advantages in the acquisition of high-resolution spectra but there is also considerable loss of information in solution compared with solid state spectra. 

Compounds 32a-c are insoluble in non-polar solvents and in the solid state the Ln(II) centers of 32a and 32c are bound by six N-donors and exhibit trigonal antiprismatic geometries and symmetry elements [73,74], Reactivity studies of 32a have been extensive and include the reduction of unsaturated organic substrates and of d-transition metal carbonyl complexes [72], The facile oxidation of 32a is highlighted by its reaction with... 

The highest oxidation states for Ir are VI and V, stabilized by ligands such as F. IrFg (a yellow crystalline solid, /Xgff = 2.9 /xb at 300 K) is formed by the direct fluorination of Ir metal. Molecules of IrFg are octahedral, and the structure has been studied in the gas phase by electron diffraction and in the solid phase by EXAFS. IrFg is hydrolyzed by water, and reactions (1 - 4) illustrate its general reactivity. Reaction four represents the formation of the first binary, tripositive metal carbonyl complex.
