AbstractSeven new diorganotin(IV) complexes, [Me2SnL] (1), [Et2SnL] (2), [(n-Bu2SnL] (3), [Ph2SnL] (4), [(n-Oct2SnL] (5), [tert-Bu2SnL] (6), and [n-BuClSnL] (7) have been synthesized from the reaction of N′-(2-hydroybenzylidene)-4-tert-butylbenzohydrazide (H2L) with the corresponding diorganotin(IV) dichloride/oxide or organotin(IV) chloride dihydroxide. The synthesized compounds were structurally
摘要七个新的二有机锡(IV)配合物,[Me 2 SnL](1),[Et 2 SnL](2),[(n -Bu 2 SnL](3),[Ph 2 SnL](4),[(n葡糖2 SNL](5),[叔-Bu 2 SNL](6),和[ ñ -BuClSnL](7从的反应已被合成)ñ ' - (2- hydroybenzylidene)-4-叔butylbenzohydrazide (H 2L)与相应的二氯化二有机锡(IV)或有机二氯化锡(IV)氯化物。合成的化合物通过FT-IR,多核NMR(1 H和13 C)光谱,元素分析,质谱,DFT /(B3LYP)计算以及配体单晶X射线衍射分析进行结构表征。光谱学证据证实配体通过亚氨基形式的氧氮供体位点与二烷基锡(IV)部分配位。的1 Ĵ(119的Sn,13 C)的偶合常数,584-655赫兹和2 Ĵ(119的Sn- 1 1H)偶合常数,79赫兹的复合物(1),
