Berechnungen zur Kinetik der Bildung von Chloro-Bromo-Iodo-Osmaten(IV)

Kinetic Calculations for the Formation of Chloro-Bromo-Iodo-Osmates(IV) Rate constants of formation and ligand exchange reactions of mixed hexahaloosmates(IV) of the type OsCl_xBr_yI_6?x?y]^2?, x + y = 2?5, are computable taking into account the relative cis- (f = 1, f = 1.75, f ≈? 6) and trans-effects (f = 1, f = 6, f ≈? 10³) of the ligands as well as statistic factors. Using this kinetic data concentration-time diagrams are calculated for reactions including several parallel and consecutive steps. They agree well with the experimentally determined distribution of products in the reaction mixtures. For the preparation of particular mixed ligand complexes the best way of synthesis and maximum yield can be precalculated.
