Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Twenty three tin(IV) tetrahalide adducts with various monodentate ligands, cis- and trans- L2·SnX4, were studied by IR and Raman spectroscopy at room temperature and above. The observed SnX stretching frequencies as well as the structure, are correlated with the donor number of the ligands. In some cases the basicity or the bulkiness of the ligand are not the prevalent factors in determining the structure of the complex. © 1982.60C219222CAPES; Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Branden, The Crystal Structure of SnCl4.2POCl3.
