Synthesis of new multitope tetrazole-containing ligands

Drawing the experience of 5-phenyl- and 5-pyridyltetrazoles, it was shown that classical nitration-reduction methods in combination with typical alkylation reactions tetrazole derivatives can be used to obtain multitopic polynuclear tetrazole-containing ligands. Methods for preparation a number previously undescribed derivatives, including those combining both pyridine rings molecule, have been developed. The composition structure obtained compounds were determined by elemental analysis, single crystal X-ray diffraction, NMR IR spectroscopy. For (5-(pyridin-2-yl)tetrazol-2-yl)(5-(pyridin-2-yl)tetrazol-1-yl)methane crystalline found this compound forms 3D polymer framework due non-classical hydrogen bonds. In its there is network π – stacking interactions between neighbouring molecules, as well rings.
