title: Intramolecular cyclization of 4,7-bis(2-bromoacetyl)-1-thia-4,7-diazacyclononane.
abstract: The reaction of 1-thia-4,7-diazacyclononane with bromoacetyl bromide in CHCl(3) affords the unexpected salt 4-(2-bromoacetyl)-8-oxo-1-thionia-4,7-diazabicyclo[5.2.2]undecane bromide, C(10)H(16)BrN(2)O(2)S(+).Br(-). Two units of the salt are linked by S.Br contacts about a crystallographic inversion centre, thus forming dimers that are linked by Br...Br contacts into extended ribbons. S...O contacts between these ribbons generate a two-dimensional sheet.
