Abstrakt: The heteroleptic anionic complex (IPrPhH)[Co2(μ-Piv)2(μ-OSiMe3)(Piv)2] (I) was synthesized through the reaction of cobalt pivalate [Co(Piv)2]n with 1,3-bis(2,6-diisopropylphenyl)-2-phenylimidazolium iodide ([IPrPhH]I) and KN(SiMe3)2 and studied by X-ray diffraction both in the solvate-free form and in the form of solvate with pentane (I⋅0.75C5H12) (CCDC 2257678–2257679). Modeling of the probable mechanism of formation of complex I and evaluation of exchange coupling between paramagnetic centers in it were carried out by density functional theory method.
