“…Таким образом, поиск подходов к синтезу новых представителей этого класса азотистых гетероциклов является весьма актуальной задачей. Ранее проведены ряд исследований в области синтетической и координационной химии производных тетразола [16][17][18][19][20][21][22][23]. Настоящая работа посвящена разработке методов синтеза новых представителей мультитопных тетразолсодержащих лигандов с использованием преимущественно классических методов органической химии.…”

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

“…The present work is a continuation of our previous research in the field of coordination chemistry of 1-monosubstituted tetrazoles with heterocyclic substituents at the N 1 position. [28][29][30] Here we report synthesis and complexation of a new potentially N,N',N''-tridentate chelating (pincer) ligand, combining in the structure two tetrazole and one pyridine rings, namely 2,6di(1H-tetrazol-1-yl)pyridine (DTP).…”

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] Since the nature and position of substituents in the tetrazole ring make a significant contribution to the variety of structural features and properties of tetrazole-containing complexes, [1] tetrazole derivatives, in which the substituent can also be coordinated by metal ions, in particular, pyridyltetrazoles are of interest as objects for research. In contrast to 5pyridyltetrazoles, whose coordination chemistry has been well studied, [15][16][17][18][19][20][21][22][23][24][25][26][27] only one publication [28] is devoted to complexation of 1-pyridyltetrazoles.…”

2,6‐Di(1H‐tetrazol‐1‐yl)pyridine (DTP) was prepared by a four‐stage procedure, including step‐by‐step heterocyclization of both amino groups of 2,6‐diaminopyridine with triethyl orthoformate and sodium azide. According to quantum‐chemical calculations and single crystal X‐ray diffraction data, DTP crystallizes in the form of the thermodynamically most stable conformer and has an almost flat molecular geometry. DTP was found to react with CuCl2 ⋅ 2H2O in ethanol to give the [Cu(DTP)Cl2(H2O)]n complex, which is a 1D coordination polymer, formed at the expense of bridging DTP ligand via the tetrazole ring nitrogen atoms N4. Possible coordination cites in DTP molecule are discussed using the data of quantum chemical calculations. The pyridine ring nitrogen atom of DTP does not participate in the formation of either coordination or intermolecular hydrogen bonds. This is explained by the results of quantum chemical calculations showing that this atom is less basic than N3 and N4 atoms of DTP molecule.
