The reaction between [ClEt2SnOSnEt2Cl]2 and 2,2′-bipyridyl has been shown to give Et2SnCl2 · bipyridyl and the tristannoxane adduct [ClEt2SnOEt2-SnOSnEt2Cl] · 12 bipyridyl. Tin-119 Mössbauer data for the tristannoxane indicate a trigonal bipyramidal geometry for all tin atoms. Crystals of Et2SnCl2 - bipy are monoclinic, space group P21/n with a  18.803(1), b  14.549(6), c  8.294(2) Å, and β  134.47(2)°. The complex has the expected...
