実験手順

A sodium cyanide adduct of tri-o-tolylborane was prepared by dissolving 2.1731 g of the tri-o-tolylborane ammonia adduct [(o-CH3C6H4)3BNH3 ] and 0.3495 g of sodium cyanide in 100 ml of distilled water, following which approximately 80 ml of ammonium hydroxide was distilled from the solution at atmospheric pressure. An additional 100 ml of distilled water was then added to the distillation flask and 100 ml of dilute ammonium hydroxide distilled therefrom. This resultant solution was then combined at room temperature under agitation with a solution prepared by dissolving 0.8608 g of nickel chloride hexahydrate in 50 ml of concentrated ammonium hydroxide (28-30% NH3). The gray precipitate which formed as the solutions were combined was collected by vacuum filtration, washed with 100 ml of concentrated ammonium hydroxide and then dried under vacuum at 50° C. for 4 hours. The product which weighed 2.4069 g was submitted for elemental analysis. The results of the analysis and the calculated formula for the complex Ni[NH3 ]4 [(NC)B(C6H4CH3 -o)3 ]2 are set forth below.
