Abstract

The complex cation [{V(daptsc)(MeOH)}2(μ-O)]2+ [daptsc2- = 2,6-diacetylpyridine bis(thiosemicarbazonate)] is the first crystallographically elucidated dimer to possess a [V2O] 6+ core, the [VIV-O-VIV]6+ structural unit, formed by cleavage of the multiple bond in the oxo-cation VO2+, is linear with the oxo group residing on a crystallographic center of inversion, and the temperature dependence of the magnetic data of the dimer is consistent with weak antiferromagnetic coupling of the d 1-d1 centers.
