A series of tin(II) salts of the types Et4N[SnX3] and Et4N[SnX2Y](X, Y = Cl, Br, or I) have been prepared, the latter for the first time. The salts are all sensitive to oxygen, their stability in this regard decreasing from SnCl3– to SnX2Y– to Snl3–. The i.r. and Raman spectra of the ions have been recorded both in the solid state and also where possible in nitromethane solution. There are signification
已经制备了一系列类型为Et 4 N [SnX 3 ]和Et 4 N [SnX 2 Y](X,Y = Cl,Br或I)的
锡(II)盐,后者是第一次。这些盐都对
氧气敏感,在这方面,它们的稳定性从SnCl 3 –降至SnX 2 Y –到Snl 3 –降低。。离子的ir和拉曼光谱既已记录在固态,也可能在
硝基甲烷溶液中记录了。属于这两种状态的数据之间存在显着差异,只有在解决方案中才能清楚地看到存在离散的
金字塔形阴离子。盐的Mössbauer光谱产生异构体位移,范围为3·47–3·95 mm./sec。相对于SnO 2 ; 为SNX轮班3 -离子增加,因为连接的卤素原子减少的electronegativites的总和。
