 Title    Substituierte Heptaarsane(3)  
 Abstract    As 7 (Mme 3)3 (M = Si, Ge, Sn) mit Nortricyclenstruktur Substituted Heptaarsanes(3) As 7 (Mme 3) 3 (M = Si, Ge, Sn) with Nortricyelene Structure The heptaarsanes(3) As 7 (Mme 3) 3 (M = Si, Ge, Sn) with nortricyclene structure have been synthesized by heterogeneous and homogeneous reactions from K 3 As 7 and Rb 3 As 7 , respectively, with Mme 3 Cl. The crystal structures have been determined. The compounds are isotypic and crystallize in unit cells of R3 symmetry, containing pairs of enantiomers. The bond lengths d(As—As) in the nortricyclene skeleton are nearly uneffected by the substituents and show the sequence typical for covalent nortricyclenes: d(basal) = 244.3 pm > d(basal-equatorial) = 242.7 pm > d(equatorial-apical) = 240.7 pm (mean values). The spread-off of the Mme, sub-stituents decreases as going from P 7 to As 7 skeletons as well as with increasing size of M.
