摘要: 测定了二个顺磁性化合物(Ph4P)[V3(mp)6](Ⅰ)和(Ph4P)2[NaV(mp)3(MeCN)(MeOH)](Ⅱ)(H2mp=邻巯基苯酚,o-HO1C6H4SH)的固态和/或溶液中的顺磁波谱。(Ⅰ)的77K固态谱及(Ⅱ)的室温固态谱均经模拟计算,认为它们的钒原子处在S=l/2的Ⅰ=7/2状态,(Ⅱ)的低温(77K)溶液谱(乙腈)与Ⅱ的固态谱相同,均有特征的八条精细结构,认为非配对电子基本上定域在钒原子的周围。

Abstract: Vanadium mercaptophenolate complexes (Ph4P)[V3(mp)6] (I) and (Ph4P)2[NaV (mp)3 (MeCN) (MeOH)]2 (Ⅱ) are paramagnetic. Their EPR spectra were measured in solution or/and in polycrystalline form at both ambient and liquid nitrogen temperatures. The simulated spectra were computed with try-or-error values of g, A, and δw (half-line width) based on the computer program. The unpaired electrons are essentially localized around the vanadium atoms.

Key words: EPR, Vanadium (IV) complex, O-mercaptophenolate
