微波甲醇溶剂热中,二丁基氧化锡与双(3,5-二叔丁基水杨醛)缩卡巴肼(H_2L~1)及缩硫代卡巴肼(H_2L~2)反应,合成了2个二丁基锡双核配合物[(Bu_2Sn)_2L]·MeOH,对其进行了元素分析、IR、~1H和~(13)C NMR结构表征。X射线晶体衍射结构表明:配合物1和2具有类似结构的双锡核配合物,Sn1和Sn2分别与配基原子构成畸形三角双锥和畸形八面体构型。相邻分子间通过O-H…N氢键作用,形成一维无限链状结构。配合物1和2对马齿苋、刺苋以及决明子等杂草的根和茎的生长具有明显的抑制作用。

The dibutyltin(IV) binuclear complexes[(Bu2Sn)2L]·MeOH have been synthesized by the microwave methanol solvothermal reactions of n-Bu2SnO and bis(3, 5-di-t-butylsalicylaldehyde) carbohydrazide (H2L1) or hiocarbohydrazide(H2L2). The structures were characterized by elemental analysis, IR, 1H NMR, 13C NMR and X-ray crystal diffraction. The crystal structure shows that the complexes 1 and 2 have a similar structure. The Sn1 are rendered five-coordination in a distorted trigonal bipyramidal structure. The Sn2 are rendered six-coordination in a dis...
