mixed ligand vanadium(III) complexes bis(acetylacetonato)(phenanthroline)vanadium(III) fluoroborate (1) and bis(acetylacetonato)(phenanthroline)vanadium(III) perchorate (2) have been prepared and characterized by UV–Vis, IR, 1H NMR spectroscopic techniques and single crystal X-ray diffraction. The electronicspectra are as expected for V(III) in an octahedral environment. The 1H NMR spectra are typical
制备了两种混合配体钒(III)配合物双(乙酰丙酮基)(菲咯啉)钒(III)氟硼酸盐(1)和双(乙酰丙酮基)(菲咯啉)钒(III)高碘酸盐(2),并通过紫外-可见,红外光谱进行了表征,1 H NMR光谱技术和单晶X射线衍射。电子光谱与八面体环境中的V(III)一样。的1 1 H NMR光谱是典型的顺磁性V(III)的物种。该配合物已经用二氯甲烷溶剂化物结晶并且是同晶的。配位球由扭曲的八面体环境中的钒组成,通过氧原子和两个菲咯啉氮与两个双齿螯合乙酰丙酮酸酯配体连接。
