Oxokationen der Übergangsmetalle

Abstract: Erwartungs-und Bestundigkeifsbereich der iibergangsnietall-Onokati~neri in waJjrigevL6sung wevden diskutiert. Besonders interessant sind Spezies rnit Bindungsordnungen der Rletall-Sauevsto,f-Bindung > I . Diese Bindungsordnungen kiinnen bisweilen rontgenogruphisch aus Bindungslangen und Bindungswinkeln, ineist aber nur IR-spktroskopisch mtersucht werden. -Der Fvequenzbereich dev Metall-Sauerstoffl Valenzschwingung, der hisher et+va von 900 bis 1100 cm-1 aiigenonimen wurde, mu$ nach &Fen Vntersrichungen bis min… Show more

“…The SO 4 modes of the V IV complexes (Figure b) are identified at 600 and 686 (ν 4 split components), 935 (bridging S−O stretch along S−O−V chain), 965 (terminal S−O stretch), and 1170 cm -1 (ν 3 ). The V IV O stretching is expected at 985 ± 50 cm -1 . , One could assign to V IV O stretching either the 965 or the 1038 cm -1 band. These two bands correspond according to the V−O stretching frequency vs bond length correlation to V−O distances of 1.61 and 1.58 Å, respectively …”

“…However, the coordination of a sixth ligand as pyridine to the complex VO(RNCS 2 ) 2 apparently displaces the sulphur atoms towards the oxygen atom with concomitant reduction of the O-V-S angles, with destabilization of the b 1 * level relative to the e p * and renders the Balhausen-Gray 13 scheme applicable to the adducts and derivatives. In the VO(RNCS 2 ) 2 complexes, the three d-d transitions are assigned to 2 B 2 ® 2 B 1 , 2 B 2 ® 2 E(I) and 2 B 2 ® 2 A 1 transitions respectively, according to the inverse energetic levels scheme proposed by Selbin 14 for a square pyramidal structure.…”
