| Abstract: | The synthesis and molecular structure of 2,6-(t-BuOCH2)2C6H3Sn(OH)]2O (2), the only second example of a monomeric tetraorganodistannoxane, is reported. Compound 2 crystallizes in two polymorphic modifications (2a, monoclinic; 2b, triclinic). The two modifications especially differ in their intramolecular Sn?Odistances which fall in the range between 2.789(3) and 3.194(5) Å. It appears, that both the latter and intramolecular O?H-O bridges (2.882(4)-2.907(6) Å) contribute to the stability of the monomeric structures. |
