A series of N2Se2 and N2Se2O2 acyclic Schiff base diselenides (3-9) have been synthesized by condensation of bis(o-formylphenyl) diselenide and amines (aniline, p-bromoaniline, benzylamine, ethanolamine, 1-aminopropanol, 2-aminophenol). The Schiff base diselenides were characterized by elemental analysis, ESI-MS, NMR (H-1, C-13, Se-77) spectroscopy and X-ray crystallography. During crystallization compound 6 afforded bis(phenyloxazoline) diselenide 9 via cyclization of Schiff base of ethanolamine. The supramolecular nature of these diselenides is studied by X-ray crystallographic structure analysis. (C) 2012 Elsevier B. V. All rights reserved.
