Studies on polygermanyl-transition metal (carbonyl) derivatives
… between the appropriate polygermanyl halides and metal carbonyl anions. The characterisation by infrared, Raman, n.m.r. and mass spectrometry of these compounds is discussed in detail. The physical properties and reactions have also been investigated and compared, in parallel with the parent …

Structural studies of polynuclear metal carbonyl derivatives
X-Ray structure analysis of fifteen metal carbonyl cluster compounds of nuclearity three to seven have been carried out to investigate the effect organo-fragments have on metal core geometry.

Novel Thienyl Dyes and related Metal Carbonyl Complexes
… for the novel thienyl dyes and related metal carbonyl complexes synthesised are then presented. This is followed by an outline of the techniques of laser flash photolysis, time-resolved infrared (TRIR) spectroscopy and time correlated single photon counting. Chapter two involves the …

Kinetics and Mechanisms of Metal Carbonyl Radical Reactions
Dinuclear metal carbonyl compounds, M(,2)(CO)(,2m)L(,2n), generally possess an intense UV absorption corresponding to a (sigma) (--->) (sigma)* transition of an electron in the metal-metal bond. Irradiation into this absorption results in formation of the (.)M(CO)(,m)L(,n) radicals with high …

Electrospray mass spectrometric analysis of transition metal carbonyl clusters
… Mass Spectrometry (ESMS) within organometallic chemistry, specifically as a technique for investigating transition metal carbonyl cluster chemistry. An initial survey of air-sensitive high-nuclearity rhodium and nickel clusters, such as [Rh9As(C0)21f and [H2Ni!2(CO)iif, demonstrated the …

The Sonochemistry of Some Metal Carbonyl Complexes (Iron, Chromium)
… sonochemical reactions. Sonication of iron pentacarbonyl, neat or in hydrocarbon solvents, produces triiron dodecacarbonyl and finely divided iron powder. The ratio of these products may be varied by changing the vapor pressure of the solvent. The mechanism for formation of triiron dodecacarbonyl …

Competing reaction pathways in the photochemical reactions of metal carbonyl compounds
The photochemical reaction of Mn$\sb2$(CO)$\sb{10}$ with HSnBu$\sb3$ has been studied by continuous photolysis. Sunlamp irradiation of a CO-saturated hexane solution of Mn$\sb2$(CO)$\sb{10}$ and HSnBu$\sb3$ results in formation of HMn(CO)$\sb5$ and Bu$\sb3$SnMn(CO)$\sb5$ in equimolar quantities. …
