Cyanocobaltate prepared at CN:Co <5:1 in water in the presence of alkali and under an atmosphere of hydrogen reacts readily with mono-olefins having electron-withdrawing substituents to give a dark red solution.Hydrogen-1 and 13C n.m.r. spectra of the solutions in D2O clearly indicate that ?-olefin complexes of cyanocobaltate are formed.The solutions also exhibit characteristic bands near 450 nm.The stoicheiometry of complex formation has been studied using PhCH=C(CN)2 and monitored by the absorbance of the complex at 440 nm.These results indicate that a new type of ?-olefin-cobalt(I) complex,
