摘要：

The preparation of trans-[Co(NH3)4(CH3NH2)Br]2+ and trans-[Co(NH3)4(CH3NH2)-(NO3)]2+ complexes is described. The UV-VIS spectra of the complexes indicate a decrease of the ligand field compared to the parent pentaammines. Infrared spectra match with the pattern of the corresponding pentaammines. The catalyzed (by Hg2+) aquation of the trans-bromomethylamine complex go under retention of the sterochemical configuration. The base hydrolysis (studied at 25-degrees-C) products show trans to cis rearrangement for both complexes. H-1 NMR spectroscopy is used for identification of the sterochemical configuration of the compounds.
