摘要：

Reaction of hexaamminecobalt(III) chloride with the silver salt of methanesulphonic acid in aqueous medium (1:3 molar ratio) forms hexaamminecobalt(III) methanesulphonate, [Co(NH3)(6)](CH3SO3)(3), in high yield. This cobalt(III) complex has been characterized by spectroscopic techniques (UV/visible, IR and NMR) and its solubility product determined. The X-ray crystal structure shows that the [Co(NH3)(6)](3+) cations interact at the second sphere by sharing edges with the CH3SO3- anions, via N-(HO)-O-... hydrogen bonds. The structure is related to that of [Co(NH3)(6)]Cl(CH3SO3)(2), but is modified to accommodate additional CH3SO3- anions in place of Cl-. (c) 2006 Elsevier B.V. All rights reserved.
