  N,N′-Linked 1,2-ethanediyl-poly(benzimidazolin-2-ones) and the X-ray crystal structure of a benzimidazolin-2-one trimer

  摘要：

  A series of N,N'-linked 1,2-ethanediyl-poly(benzimidazolin-2-ones) that can be classified as podands, are described. Seven dimers (21-27), three trimers (28-30), a cyclic tetramer (31) and an open-chain benzimidazolin-2-one heptamer (32) have been prepared and characterized by H-1, C-13 NMR and by MS, The crystal and molecular structure of the trimer, 1,3-bis-2-(2-oxobenzimidazol-1-yl)ethyl-2-oxobenzimide monohydrate (30) has been solved by X-Ray analysis. The benzimidazolin-2-one fragments display a pattern of bond distances and angles similar to that of analogue derivatives retrieved form the CSD. The molecules are hydrogen bonded to four others in a continuous two-dimensional network by N-H ... O=C and C-H ... O=C interactions in which all N-H donors and O=C accepters are involved.
