Abstract
Chloropentaamminecobalt(III) chloride, chloropentaamminerhodium(III) chloride and chloropentaammineiridium (III) chloride labelled with Cl in the cation have been irradiated with thermal neutrons in a flux of 10 neutrons cm 2 sec -1 for ten hours. Study of the effects of the (η, γ) reaction has shown that , in the case of the cobalt and rhodium complexes, there is retention of the "CI in the cation, but in the case of the iridium complex about 90% of the Ir-Cl bonds are broken whilst only one in 10 iridium atoms are activated. The results are interpreted using a modification to the hot zone theory of HARBOTTLE and SUTIN. An attempt has been made to identify some of the species formed upon dissolution in water.
