Abstract

The complexes [Co(DioxH)2L2][SbF6] · nH2O, where DioxH is dimethylglyoxime monoanion (DioxH−) or 1,2-cyclohexanedione dioxime (NioxH−), L is aniline (An) or triphenylphosphine (PPh3), were isolated from the CoX2 · nH2O-NaSbF6-DioxH2-L system (X = F or CH3COO) in aqueous methanol. The complexes were studied by UV, IR, and NMR spectroscopy and by X-ray diffraction. The crystal structure of [Co(DH)2(An)2][SbF6] · H2O (I) and [Co(NioxH)2(PPh3)2][SbF6] (II) is stabilized by the electrostatic interactions between the Co(III) complex cations and outer-sphere fluorine-containing anions and by hydrogen bonds between structural units.
