Structural and spectral studies of hydrated hexaamminecobalt(III)–hexafluororhenate(IV)
The crystal structure of the [Co(NH 3 ) 6 ] 2 [ReF 6 ] 3 ·3H 2 O (I) salt is reported. The salt crystallizes in the trigonal space group P31m with the following unit cell dimensions: a = 15.8714(4) Å, b = 15.8714(4) Å, and c = 9.8657(4) Å. Here, the structure of (I) consists of [Co(NH 3 ) 6 ] 3+ cations, [ReF 6 ] 2– anions, and co-crystallized water molecules which are linked by hydrogen bonding. In (I), independent [ReF 6 ] 2– anions and [Co(NH 3 ) 6 ] 3+ cations octahedron are slightly distorted. Characteristic vibration bands of the [Co(NH 3 ) 6 ] 3+ cation, [ReF 6 ] 2– anion as well as the co-crystallized H 2 O molecules are observed in the infrared spectra of (I). UV-Visible analyses in water showed that the absorption of the [Co(NH 3 ) 6 ] 3+ cation predominate the spectra of (I).
