 Title    (MeSn)4Se6, Geometrie und Schwingungsformen eines Adamantan-Gerüstes aus Zinn-Selen-Bindungen (MeSn)4Se6, Geometry and Vibrational Modes of an Adamantane Framework Formed by Tin-Selenium Bonds  
 Abstract    The title compound has been synthesized by reaction of MeSnBra and NaHSe in aqueous solution. The X-ray structure determination showed adamantane-like molecules (Sn-Se 253(1), Sn-C 215(1) pm) arranged in a quasi hexagonal-close packing. The atomic coordinates were used for an analysis of the vibrational spectra, yielding information on the distribution of the potential energy for the normal modes in terms of internal co-ordinates and a set of force constants. The valence force constants f(Sn-Se) 154(6), f(Sn-C) 216(2) N/m) are compared with those in related monocyclic molecules.
