Scandium atoms reacting with

Figures 4 and 5 Illustrate the chemistry of iron and scandium atoms reacting with water. As noted earlier, both Fe and Fe2 water adducts are formed and labeled "a" and "b", respectively, in Figure A. It is interesting that Fe2...0H2 can be photolyzed without photolyzing the Fe...OH2 adduct. The "d" peaks which result from photolysis of Fe2...0H2 indicate that a species with terminally bonded H and OH groups is formed. The photolysis of Fe2...0H2 would appear to lead to formation of the HFeFeOH species.

Laser-ablated scandium atoms react with MeOH to form matrix-trapped products, including MeOScH, for which IR assignments are summarised in Table 1 (data referring to an argon matrix).1... 

Laser-ablated scandium atoms react with MeOH to form (MeO)ScH. Ma-trix-IR data for this species gave the following assignments 8CH3 1167.4 cm-1, vC-0 1158.5 cm 1.393... 

Cyclopentadienylamine)scandium(2,3-dimethyl-l,3-butadiene) 7 was synthesized in good yield, as shown in Scheme 2. Complex 7 reacted with benzonitrile to form a /rz-imido complex 8, the structure of which was characterized by single crystal X-ray diffraction. This product 8 was proposed to be formed by nitrile insertion followed by an attack of another diene methylene group on the carbon atom of the imido intermediate.3 An unsaturated metal imido species was formed, which easily dimerized to produce 8. However, the yield of 8 was not reported. 

Relatively few complexes of N-donor ligands are known. One of the best characterized is with the tridentate ligand terpyridyl, which reacts with scandium nitrate to form Sc(terpy )(N03 )s here scandium is connected to 9 atoms, but one Sc-O bond is considerably longer than the others, so a coordination number of 8.5 has been assigned. A range of porphyrin and phthalocyanine complexes exist syntheses often involve the high-temperature routes typical of the transition metals but recently a high-yield low-temperature route has been utilized to make octaethylporphyrin (OEP) complexes ...
