New organotin(IV) bromides containing potential donor ligands. Synthesis, characterization and supramolecular architecture

摘要: Abstract The protective acetal group in [2-{(CH2O)2CH}C6H4]SnMe2Br (1) was removed by hydrolysis to give [2-(O CH)C6H4]SnMe2Br (2). Reaction of 2 with the appropriate amines, absence a solvent or catalyst, afforded isolation high yields [2-(RN [R = 4′-{MeO(O)C}C6H4 (3), 2′-PyCH2 (4), 4′-PyCH2 (5)]. All compounds were characterised multinuclear NMR and IR spectroscopies as well mass spectrometry. molecular structures 1, 3, 4 5 established single crystal X-ray diffraction analysis. For all organotin(IV) bromides intramolecular O→Sn Nimine→Sn coordination results hypercoordinated species distorted trigonal bipyramidal metallic centre. Supramolecular associations based on C H⋯Br, H⋯π (Arcentroid) and/or (Pycentroid) intermolecular interactions are formed solid state for compounds, i.e. double chain, ribbon-like polymer complex 3D architectures.
