route of obtaining very stable octacoordinated non-oxovanadium(IV) complexes of the general formula VL2 (where H2L is a tetradentate ONNO donor) is presented. Six such complexes (1-6) are adequately characterized by elemental analysis, mass spectrometry, and various spectroscopic techniques. One of these compounds (1) has been structurally characterized. The molecule has crystallographic symmetry and
提出了获得通式VL2(其中H2L是四齿ONNO供体)的非常稳定的八配位非氧钒(IV)配合物的简单通用路线。六种此类配合物(1-6)通过元素分析,质谱和各种光谱学技术进行了充分表征。这些化合物(1)之一已在结构上得到了表征。该分子具有晶体对称性,并具有存在于四边形空间群Pn2中的十二面体结构。从分析和质谱数据确定所有配合物的非羰基特征和VL2化学计量。此外,在925-1025 cm-1区域完全不存在强nuV = O谱带,清楚地表明了其非氧羰基特征,这是所有氧钒基物种的标志。
