Structural and Thermal Studies of New Triphenyltin Complexes

[Image: see text] Crystal and molecular structures of new triorganotin complexes have been determined via X-ray diffraction. These complexes include, among others, the second polymorph of Ph(3)Sn(thiocytosine), the double complex salt Ph(3)Sn(methimazole)(2)·Ph(3)SnCl(2), and five-coordinated triphenyltin chloride with methimazole, tetrahydopyrimidine-2-thione, dimethylformamide, and dimethyl sulfoxide. Hirshfeld surface analysis allowed for better visualization and precise pinpointing of the differences between polymorphs as well as easier analysis of intermolecular interactions. All of the new structure of the Ph(3)Sn(L)Cl type displayed interesting thermal features and therefore were also analyzed via thermogravimetric analysis/simultaneous thermal analysis/differential scanning calorimetry methods. These analyses showed the different ways in which these complexes underwent thermal decomposition. In some cases, to solve the problems that arose, powder X-ray diffraction analyses have also been performed.
