Zusammenfassung:	Disclosed is a method for producing multimetal cyanide compounds, comprising the following steps: a) the aqueous solution of a metallic salt of general formula (I) M1gXn (I) is reacted with the aqueous solution of a cyanometallate compound of general formula (II) M3r[M2(CN)b]d, (II), optionally in the presence of organic ligands, organic additives, and/or surfactants, to a multimetal cyanide compound of general formula (III) M1a[M2(CN)b]d.fM1jXk.h(H20).eL.zP; b) the multimetal cyanide compound of general formula (III) is reacted with a salt of general formula (IV) M4sYt (IV), which is different from (II) and wherein Y represents an anion that is different from X while M4 represents alkali metal ions or an ammonium ion (NH4+) or alkyl ammonium ion (R4N+, R3NH+, R2NH2+, RNH3+, whereinR=C1-C20 alkyl). Also disclosed are compounds that can be obtained by means of said method as well as the use thereof as catalysts for producing polyether alcohols.
