EnglishSpirocyclic bis(ethane-1,2-dithiolato[2-]-SS')tin(IV) forms hexacoordinate crystalline complexes with pyridine and 2-(2-pyridyl)ethylamine. The compounds have been prepared by conventional methods and the crystal structures have been determined by an X-ray diffraction study. In the parent compound the tin is tetracoordinate in a highly distorted tetrahedral structure, with a weak intermolecular Sn ... S interaction. On the contrary, the adducts are essentially octahedral about the tin, with longer Sn-S bonds in the five-membered rings SnS2C2. The 2-(2-pyridyl)ethylamine ligand is bonded to the metal through the aminic nitrogen.

In the parent compound the tin is tetracoordinate in a highly distorted tetrahedral structure, with a weak intermolecular Sn ... S interaction. On the contrary, the adducts are essentially octahedral about the tin, with longer Sn-S bonds in the five-membered rings SnS2C2.
