Compounds that form in the CoSiF6· 6H2O–NioxH2–A–water–alcohol system, where A is thiourea (Thio) or triphenylphosphine (PPh3) and NioxH2is 1,2-cyclohexanedione dioxime, were synthesized and characterized by X-ray diffraction analysis. Crystal structures of the [Co(NioxH)2(PPh3)2]SiF5and [Co(NioxH)2(Thio)2]2SiF6· 3H2O complexes were established. In octahedral Co(III) complexes, two radicals of 1,2-cyclohexanedione dioxime are bound by a hydrogen bond and are located in the equatorial plane. The intramolecular (π–π and H bonds) and intermolecular (C–H···F and H bonds) interactions in the crystal are discussed. |
