The first X-ray structure of a hexaamminecobalt(III) salt with two different complex chlorocadmium anions: synthesis, characterization and crystal structure of [Co(NH3)6]4[CdCl6][CdCl4(SCN)(H2O)]2Cl2.2H2O.

In the title complex salt, tetrakis[hexaamminecobalt(III)] hexachlorocadmate(II) bis[aquatetrachlorothiocyanatocadmate(II)] dichloride dihydrate, the discrete ions, i.e. [Co(NH3)6]3+, Cl-, [CdCl6]4- (located on an inversion centre) and [CdCl4(SCN)(H2O)]3-, together with cocrystallized water molecules, are assembled by means of a network of hydrogen-bonding interactions. This is the first X-ray structure determination of a hexaamminecobalt(III) salt with two different complex chlorocadmium anions.
