Crystal and molecular structure of β-(N-benzoxazoline-2-thione) propionic acid and its salts

详细

The crystal and molecular structures of β-(N-benzoxazoline-2-thione)propionic acid, its monoethanolammonium (NН₂(CH₂)₂OH) and ethylenediammonium (NН₂(CH₂)₂NH₂) salts are studied. In the salts the monoethyleneamine amine group participates in the deprotonation of one ethylenediamine–two β-(N-benzthiazolin-2-one)propionic acid molecules. The geometry of the molecules and intermolecular hydrogen and donor-acceptor bonds in crystals are analyzed. In the crystal structures weak interactions form a two-dimensional layer whose thickness corresponds to unit cell sizes.
