Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain the subject new complex useful as a catalyst enabling to produce polyetherpolyols extremely narrow in short induction periods by reacting a zinc salt and a metal salt with a metal hexacyano cobalate. SOLUTION: A new zinc/metal hexacyanocobaltate complex of formula I [M is a divalent metal atom comprising Cd, Hg, Pd, Pt, V, Mg, Ca, Ba, Fe, Ni, Mn, Co, Sn, Pb, Sr or Co; X, Y are each a halide, OH, sulfate, carbonate, isocyante, carboxylate, etc.; L is an organic complex ligand derived from an alcohol, an aldehyde, a ketone, an ether, an ester, an amide, etc.; (v) is 0.005-2.995; (w) is 0.1-10; (x) is 0.01-10; (y), (z) are each 0.001-3.0; (m), (n) are each 1, 2]. The complex of formula I is obtained by reacting the aqueous solution of a zinc salt of the formula: Zn(X)n and a metal salt of the formula: M(Y)n with a cobalt cyanide salt of formula II [M' is an alkali (ne earth) metal] in the presence of a lignad of the formula: L.
