Zusammenfassung:	Metal [hexacyanometallate hexanitrometallate] complexes are useful alkylene oxide polymerization catalysts. The metal is any that forms a precipitate with hexacyanometallate and hexanitrometallate groups. These catalysts are made from less expensive raw materials than the common zinc hexacyanocobaltate catalysts, and provide short induction periods and in many cases more controlled exotherms. Los complejos de [hexacianometalato hexanitrometalato] metalicos son catalizadores de polimerizacion de oxido de alquileno. El metal es cualquiera que forma un precipitado con grupos hexacianometalato y hexanitrometalato. Estos catalizadores se hacen de materiales primas menos costosas que los catalizadores de hexacianocobaltato de zinc comunes, y proporcionan cortos periodos de induccion y en muchos casos exotermos mas controlados.
