Depending on the solvent ratio MeCN: EtOH, the reaction of [VO(H2O)5](otf)2 (otf = O3SCF3) with 1,10-phenanthroline (phen) and lithium pentafluorobenzoate (Li(O2C2C6F5) = Li(pfbz)) affords crystals of heteronuclear compound [Li2(VO)2(µ-pfbz)6(phen)2]·2MeCN (1), mononuclear complex [VO(pfbz)(phen)2](otf) (2) and binuclear complex [(VO)2(μ-OH)(μ-pfbz)2(phen)2](otf)·MeCN·H2O (3). The structures of new compounds 1–3 were determined by X-ray diffraction. According to magnetochemical and EPR spectroscopy data, the paramagnetic VIV centers in structures 1 and 2 are magnetically isolated, and in compound 3, spin–spin antiferromagnetic exchange interactions between vanadium ions are realized (J = –138 cm−1).
