Metals energy

The chemistry of the transition metals is determined in part by their atomic ionization energies. Metals of the 3d and 4d series show a gradual increase in ionization energy with atomic number (Z), whereas the trend for the 5d series is more pronounced (Figure 20-3). First ionization energies for transition metals in the 3d and 4d series are between 650 and 750 kJ/mol, somewhat higher than the values for Group 2 alkaline earth metals but lower than the typical values for nonmetals in the p block. [Pg.1431]

Similarly, treatment of a hexane solution of (77-C5Me5)2TiCl with CO at room temperature gave the thermally unstable adduct (17-C5Me5)2Ti(CO)(Cl) (52) as evidenced by again a high energy metal carbonyl band at 2000 cm-1 (98). Complex 52 slowly disproportionated at... [Pg.364]

The high energy metal carbonyl band would be consistent with a Ti(IV) cationic complex, while the C=N bands correspond closely to those of the (TCNE)2 dianion at 2160 and 2095 cm-1 and also to those in (PPh3)2-(CO)IrN=C=C(CN)C(CN)=C=NIr(CO)(PPh3)2. [Pg.365]

Treatment of a hexane solution of the 16-e- complex, (i7-C5Me5)2HfH2, with CO at -35°C resulted in formation of the thermally unstable (i7-C5Me5)Hf (H)2(CO) as evidenced by the appearance of a high energy metal carbonyl band at 2036 cm-1 in its IR spectrum (70). As the solution warmed, this band decreased in intensity concurrent with the appearance of metal carbonyl bands at 1941 and 1850 cm 1 assignable to (17-C5Me5)2Hf(CO)2 (33) (70,72). [Pg.372]

These tru 5-dioxoruthenium(VI) complexes have characteristic UV-vis absorption spectra. The fj-saturated nature of the macrocyclic tertiary amine ligands enables the high-energy metal-localized transition to be observed. " The weak vibronic structured band at 370-400nm has been assigned to (0 ) —> Ru charge transfer transition that is vibronically coupled to the... [Pg.774]

The low-energy metal to ligand charge-transfer (MLCT) excited state has been extensively studied and involves low-lying ft -acceptor orbitals of the pyridine ligands ( ). ... [Pg.165]

Low-valence transition metal complexes of a-diimine ligands are highly colored because of the presence of low-energy metal to a-diimine charge transfer (MLCT) transitions. For a series of d6-M(CO)., (a-diimine) (M=Cr,Mo,W) and d8- M (CO)3 (a-diimine) (M =Fe, Ru) complexes, we have studied the spectroscopic and photochemical properties (1-10). The a-diimine ligands used are 1,4-diaza-1,3-butadiene (R-DAB), pyridine-2-car-baldehyde-imine (PyCa), 2,2 -bipyridine (bipy) or 1,10-phenanthroline (phen) molecules. A close relationship was deduced between the photochemical behavior of these complexes and their resonance Raman (rR) spectra, obtained by excitation into the low-energy MLCT band. [Pg.66]

Due to low ionization energies, metals have a tendency to lose valence electrons relatively easily, whereas non-metals, which have high ionization energies and high electronegativites, gain electrons easily. [Pg.119]
