Chemistry of the metal carbonato complexes

Hydrogenation of a Rhodium Peroxido Complex by Formate Derivatives: Mechanistic Studies and the Catalytic Formation of H2O2 from O2

“…4 Hz. [23] The structure of 5 a in the solid state was determined by X-ray crystallography (Figure 1). [10,13,16] The absorption bands at 673 cm À1 for 5 a, as well as 674 cm À1 , 662 cm À1 , and 649 cm À1 for 5 b can tentatively be assigned to in-plane deformation vibrations of the Rh{k 2 -OC(O)O} moiety.…”

Kinetics and mechanism of the acid-catalysed hydrolysis of the carbonatotetraimidazolecobalt(III) ion

“…Qualitative conclusions concerning the basicity of the coordinated carbonato can be drawn based on the C=O stretching vibration (15,21). Comparison of these frequencies shows their correlation with protonation constant values, K. The rate constants k 1 are close for histamine and ethylenediamine complexes, and ca.…”

NMR study of the coordinating behavior of 2,6-bis(benzimidazol-2?-yl)pyridine

“…The anions of benzimidazole and 2,6-bis(2-benzimidazol-2Ј-yl)pyridine were handled under an N 2 atmosphere using carefully dried glassware and dried solvents. [Co(NH 3 ) 4 CO 3 ]NO 3 was synthesized as described in the literature [24]. 2,6-Bis(2-benzimidazol-2Ј-yl)pyridine and ethanol were analytical grade reagents obtained from Aldrich and used without further purification.…”
