Abstract:
(l) Metal exchange has been observed for some aliphatic Schiff base complexes of nickel.
(2) A previously unreported method of radioassay for Ni63 has been developed, using a scintillation counting technique.
(3) Stepwise formation of five and six co-ordinate species has been observed for two of the complex compounds with ammonia. Where k2, the second formation constant, has been determined, it is greater than k1.
