    Abstract: The invention relates to a crystalline multi-metal cyanide complex of general formula (I) M1aM2(CN)bL1c!d*e(M1fXg)*hL2'iH2O, in which M1 represents at least one element from the group comprised of Zn(II), Fe(II), Co(III), Ni(II), Mn(II), Co(II), Sn(II), Pb(II), Fe(III), Mo(IV), Mo(VI), Al(III), V(IV), V(V), Sr(II), W(IV), W(VI), Cu(II) and Cr(III). M2 represents at least one element from the group comprised of Fe(II), Fe (III), Co(III), Cr(III), Mn(II), Mn(III), Ir(III), Rh(III), Ru(II), V(IV), V(V), Co(II) and Cr(II). L1 represents at least one ligand from the group comprised of cyanide, carbonyl, cyanate, isocyanate, nitrile, thiocyanate and nitrosyl. X represents one formate anion, acetate anion or propionate anion. L2 represents one ligand which is mixable with water and from the group comprised of alcohols, aldhydes, ketones, ethers, polyethers, esters, urea derivatives, amides, nitriles and sulfides. a, b, c, d, e, f, g, h, i are whole numbers, whereby a, b, c and d are selected such that the electroneutrality condition is fulfilled and f and g are selected such that the electroneutrality condition is also fulfilled. According to the invention, the inventive complex has x-ray diffractogram reflexes at determined d-values and can be used as a catalyst.

    Abstract: The invention relates to polyether alcohols that are produced by a ring-opening polymerization of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule to H-functional starting substances. The inventive method is further characterized in that ethylene oxide or a mixture of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule with an ethylene oxide content of at least 98 %, based on the mixture, is added to the starting substance in an amount of maximally 40 % by weight, based on the weight of the polyether alcohol. At least one alkylene oxide with at least 3 carbon atoms in the molecule or a mixture of ethylene oxide and at least one alkylene oxide with at least 3 carbon atoms in the molecule and an ethylene oxide content of maximally 20 % by weight, based on the mixture, is added.
