 Title    Cyclische Diazastannylene, X [1] Die Kristall-und Molekülstruktur eines Moleküls mit verzerrt-würfelförmigem Sn4N30-Käfig Cyclic Diazastannylenes, X [1] The Crystal and Molecular Structure of a Molecule with a Distorted Cube-Shaped SiLiNsO-Cage  
 Abstract    The crystal and molecular structure of (me3CN)3(me3A10)Sn4 has been determined from three-dimensional X-ray data (4-circle diffractometer, R — 0.048). The crystals are mono-clinic, space group P2i/c, with cell dimensions a = 1017.4(5), b — 1488.5(7), c = 1748(1) pm, jS—91.5(1)° and Z — 4. The molecules approach 3m point-symmetry and include a SruNsO-cage, the atoms occupying the corners of a distorted cube formed by two, differently sized, interpenetrating concentric tetrahedra of tin and nitrogen/oxygen atoms. The nitrogen atoms are attached to tert-butyl groups, whereas the oxygen atom of the cage acts as a base towards the aluminiumtrimethyl group. Typical bond distances and angles (mean values) are: Sn-N = 219.9, Sn-0 = 220.3 pm; N-Sn-N = 81.2°; N-Sn-0 = 79.0°; Sn-N-Sn = 98.8° and Sn-O-Sn -100.2°.
