Abstract:
1. A process for preparing a multimetal cyanide compound, wherein said process comprises: a) reaction of the aqueous solution of a metal salt of the general formula (I) with the aqueous solution of a cyanometalate compound of the general formula (II) optionally in the presence of an organic ligand, an organic additive and/or a surface-active agent, to form a multimetal cyanide compound of the general formula (III) b) reaction of the multimetal cyanide compound of the general formula (III) with a salt of the general formula (IV) which is different from (II) where wherein the multimetal cyanide compound is separated off from the aqueous phase between a) and b) and the pH of the aqueous solution of the salt (IV) is from 4 to 7.
