| Popis: | A number of oxo-centred trinuclear complexes have been obtained, of general formula [M3O(OOCR)6L3]X (R˭H, CH3; M˭Cr(III), Fe(III); L=pyridine, 4-picoline; X˭NO− 3, ClO− 4). The behaviour of these compounds in absolute methanol and in dimethylsulphoxide was investigated by the conductometric method. Dissociation constants of the complexes were determined. Molar conductivities and solvodynamic radii of the cations were also evaluated. It has been shown that the cations do not undergo solvation to any measurable extent. |
