H2O (5a) and molecular structures of 1a and N(CH2CH2CH2)(3)SnX (2, X = Cl; 3, X = Br; 4, X = I) are reported. Compound la is a tetramer held together by intermolecular Sn...F interactions (2.797(6) Angstrom) and F...H and O...H hydrogen bridges. It is the first example of an intermolecular hexacoordinated triorganotin halide. Compounds 2-4 exhibit the expected propellane (metallatrane) structure with pentaccordinate tin, with the shortest intramolecular Sn...N interaction of 2.28(2) Angstrom found for 3. The Sn...N distances in the other stannatranes are 2.393(5) and 2.426(6) (1a), 2.38(2) (2, hexagonal), 2.38(4) (2, monoclinic), and 2.375(6) Angstrom (4). » weiterlesen» einklappen
