| description | A crystal structure and thermal characterization of a multisite Schiff base containing N<sub>2</sub>O<sub>2</sub>-inner and O<sub>4</sub>-outer coordination sites are reported. The title compound was characterized by X-ray structure analysis, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR and ATR-FTIR spectroscopy, TG/DSC and TG-FTIR techniques. The compound crystallizes as a methanol solvate in the triclinic system, space group <i>P</i><inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mover accent="true"><mrow><mn>1</mn></mrow><mo>¯</mo></mover></mrow></semantics></math></inline-formula>. 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. |
