摘　　要：测定了二个顺磁性化合物(Ph_1P)[V_2(mp)_6](Ⅰ)和(Ph_4P)_2[NaV(mp)_3 (MeCN)(MeOH)](Ⅱ)(H_2mp=邻巯基苯酚,o-HO_1C_6H_4SH)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。Vanadium mercaptophenolate complexes (Ph_4P) [V_3(mp)_6] (I) and (Ph_4P)_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.
