Abstract

The reaction of cobalt pivalate [Co(Piv)2]n and in situ generated N‑heterocyclic carbene IPrPh (1,3-bis(2,6-diisopropylphenyl)-2-phenylimidazol-4-ylidene) affords heteroligand complexes [Co2(Piv)4-(IPrPh)2] (I), [Co2(Piv)2.8(OtBu)1.2(IPrPh)2] (II), and [Co3(μ3-O)(Piv)4(IPrPh)2] (III). The structures of complexes II·C6H14 and III are determined by X-ray diffraction (XRD) (CIF files CCDC nos. 2216724 and 2216725, respectively). Exchange spin-spin interactions between the magnetic Со2+ ions in the synthesized compounds are estimated by quantum chemical calculations.
