✦ Synopsis

The relative metal ion (Ni' and Co') affinities of 14 alkanenitriles, alkenenitriles and benzonitrile were estimated using Cooks' kinetic method in a fast atom bombardment mass spectrometer. The results are compared with proton affinities, affinities for other metal ions, two-ligand dissociation enthalpies and the dipole moments of the nitriles. The RCN-Co' bond is found to be close to the RCN-Ni' bond but weaker than the RCN-AI' bond.

The effective temperature ( T ) of the metal-bound dimer ions falls in the range 298 K < T < 400 K.
