| Abstract: | The complex compounds Co(DH)2(Anil)2]BF4] and Co(DH)2(Py)2]BF4] were synthesized from Co(BF4)2 · 6H2O–DH2–A–alcohol–water systems (DH2 is dimethylglyoxim and A is pyridine (Py) or aniline (Anil)), and their crystal structures were determined using X-ray diffraction analysis. In octahedral Co(III) complexes, two dimethylglyoxime radicals lie in the equatorial plane and are joined via the intramolecular hydrogen bond O–H···O. The complexes with pyridine and aniline have similar configurations but different crystal structures. |
