  四卤化锡（IV）与中性路易斯碱的加合物。一，溶液中顺反异构现象的振动研究

  摘要：

  摘要合成并分析了大量的SnX4·2L和SnX4·LL四卤化锡（IV）加合物（X = Cl，Br; L = Me2O，Et2O，THF，Me2S，Et2S，THT，Me2Se，MeCN，Me3CCN，Me3CO ，HMPA，TMPA； L =（MeOCH2-）2）。它们的顺式或反式几何结构通过红外和拉曼光谱法测定。对于SnCl4·2THT加合物，可以通过改变溶剂极性来分离两种异构体。对于大多数加合物，通过拉曼测量已证明溶液中存在顺式-反式平衡。这种平衡在很大程度上取决于溶剂的极性，顺式异构体在高极性介质中是有利的。使用威尔逊FG矩阵的简化模型，确定Sn-X力常数，并推导以下序列以得出SnX4·2L中锡-配体键的强度：Me2Se> Me2S〜THT〜Et2S>

  The 35Cl n.q.r. spectra of a series of tin(IV) chloride adducts SnCl4·2L [L = MeCN, CH2CHCN, ButCN, PhCN′ CH2(CN)2, 1,2-C6H4(CN)2, SMe2O, or tht (tetrahydrothiophen)] have been recorded at various temperatures and used to deduce whether these complexes are cis or trans. A trans structure is indicated for SnCl4·2tht, cis structures for the remainder. When compared with other published n.q.r. and structural

  Complexes of tin, antimony, silicon, germanium, iodine, boron and titanium halogenides with organic ligands were investigated using nuclear quadrupole resonance (NQR) and X-ray fluorescence spectroscopies, and Mossbauer effect and quantum-chemical calculations. A discussion of results which we obtained previously as well as literature data is included. The correlations between Cl-35 NQR and ClKalpha line shifts in SnCl4L2, SbCl5L and TiCl4L2 complexes were obtained. The geometry of the acceptor was found to influence the value of the effective charge on the chlorine atom (q(Cl)) in SnCl4L2 complexes, but not to influence the chlorine atom in TiCl4L2 complexes. Values of q(Sn) and q(Sb) were calculated from Mossbauer isomer shifts in the SnCl4L2 and SbCl5L complexes. Electron-density transfer from the ligand to the vacant d orbital of the central atom on complexation was observed.
