20 m moles of nickel acetylacetonate was suspended in 20 ml of n-hexane and 20 ml of 1,5-cyclooctadiene, and an n-hexane solution containing 100 m moles of diethyl aluminum ethoxide [(C2H5)2AlOC2H5 ] was added dropwise thereto at a temperature of -5° to -10° C. The resulting yellow colored crystals were filtered out and then recrystallized from benzene. Thus, bis-cyclooctadiene nickel was obtained.
