Heteropolytopic oxalyl and malonyl diamide ligands, derived from 1H-pyrazole, 3,5-dimethyl-1H-pyrazole, 1H-indazole and 1H-1,2,3-benzotriazole, have been synthesised by reaction of the corresponding azole with oxalyldichloride and carbon suboxide respectively and fully characterized by elemental analyses, IR and NMR (1H, 13C).

Abstract
Heteropolytopic oxalyl and malonyl diamide ligands, derived from 1H-pyrazole, 3,5-dimethyl-1H-pyrazole, 1H-indazole and 1H-1,2,3-benzotriazole, have been synthesised by reaction of the corresponding azole with oxalyldichloride and carbon suboxide respectively and fully characterized by elemental analyses, IR and NMR (1H, 13C). In the examined cases single crystal X-ray diffraction studies revealed important supramolecular assemblies based on H-bonds and/or π-π interactions. The reactivity behaviour toward metal salts is also described.File in questo prodotto:
