A series of new coordination compounds of cobalt(III) trans-dioximates with pyrazine [CoCl(DH)2Pz] · H2O (I), [CoBr(DH) 2Pz] · H2O (II), [Co(DH)2Pz 2]NO3 · H2O (III), [Co(DH) 2Pz2][BF4] (IV), [Co(MgH)2Pz 2][BF4] (V), and [Co(NioxH)2Pz 2][BF4] (VI),where DH, MgH, and NioxH are dimethylglyoxime, methylglyoxime, and 1,2-cyclohexanedionedioxime monoanions, respectively, Pz is a pyrazine molecule were synthesized. The structures of compounds I, II, and VI were determined by X-ray diffraction. The Co(III) environment in these compounds is octahedral and the pseudomacrocyclic (DioxH-)2 fragment occurs in the equatorial plane. This fragment is stabilized by O-H...O hydrogen bonds. The neutral Pz ligand is monodentate in all three compounds. |
