N , N ′-Bis(3-ethoxy-2-hydroxybenzylidene)-phenylene-1,3-diamine Methanol Solvate.

A crystal structure and thermal characterization of a multisite Schiff base containing N2O2-inner and O4-outer coordination sites are reported. The title compound was characterized by X-ray structure analysis, 1H-NMR, 13C-NMR and ATR-FTIR spectroscopy, TG/DSC and TG-FTIR techniques. The compound crystallizes as a methanol solvate in the triclinic system, space group P 1 ¯ . The stable at room temperature compound, during heating in the air, first loses a methanol molecule. At higher temperature, the sample decomposition is associated with a strong exothermic effect and the emission of large amounts of carbon dioxide, carbon monoxide and ammonia. [ABSTRACT FROM AUTHOR]
