Zusammenfassung:	A zinc/metal-hexacyanocobaltate catalyst (I) is of formula Zn3-vMvÄCo(CN)6.w(H2O).x(L).y ÄZn(X)nÜ.ZÄM(Y)mÜ(I). Also claimed is a process for the preparation of (I) by mixing a 1-90 wt.% aqueous solution of a zinc salt of formula Zn(X)n and a metal salt of formula M(Y)m with a 0.5-50 wt.% aqueous solution of a cobalt (III) cyanide salt of formula M 3ÄCo(CN)6Ür in the presence of an organic complex ligand of formula L whereby the molar ratio of zinc and metal to cobalt is 2:1 - 10:1 and the molar ratio of zinc and metal to L is 1:100 - 100:1 and the molar ratio of zinc salt to metal salt is 500:1 - 1:500. M = Cd(II), Hg(II), Pd(II), Pt(II), V(II), Mg(II), ca(II), Ba(II), Fe(II), Ni(II), Mn(II), Co(II), Sn(II), Pb(II), Sr(II) or Cu(II) X,Y = halide, hydroxy, sulphate, carbonate, cyanate, thiocyanate, isocyanate, isothiocyanate, carboxylate, oxalate, or nitrate L = an organic complex ligand consisting of alcohol, aldehyde, ketone, ether, ester, amide, urea, nitrile or sulphate. v = 0.005-2.995; w = 0.1-10; x = 0.01-10; y = 0.001-3.0; z = 0.001-3.0; m and n = 1 or 2.
