“…105 dicyanohydrazine is accompanied by cleavage of the N7N bond to give (5-aminotetrazolato)hydroxyzinc (94). 106 In the case of terephthalonitrile and 3,4-dicyanopyridine, the reaction in the presence of manganese salts is limited to azidation of only one cyano group to give complexes 95 107 and 96 98 in which the tetrazolate anion is not involved in coordination (X-ray diffraction data). A similar structure has been found for some other tetrazole-containing manganese aqua complexes.…”

Published data on the synthesis, structure, properties Published data on the synthesis, structure, properties and applications of metal derivatives of tetrazoles are generalised and applications of metal derivatives of tetrazoles are generalised and described systematically. Compounds based on the anionic and described systematically. Compounds based on the anionic and neutral tetrazole forms, and neutral tetrazole forms, C C-and -and N N-mono-and -mono-and C C, ,N N-disubsti--disubstituted tetrazoles are considered. The bibliography includes 464 tuted tetrazoles are considered. The bibliography includes 464 references references. . ReceivedDepending on the reaction conditions, meta-and para-5,5 Hphenyleneditetrazoles 25 react with Cd, Zn and Mn(II) salts to give essentially different, as regards both composition and structure, complexes 26, 27, 44 28, 45 29. 46 The structures of compounds 26 ± 29 were determined by X-ray diffraction. Compounds 26 ± 28 in which the doubly charged anions derived from tetrazole 25 function as bridges are two-and three-dimensional coordination polymers. Conversely, compound 29 is a mononuclear aqua complex containing no metal ± tetrazole coordination bond. In the structure of complex 28, one-dimensional channels were found which occupy up to 35% of the void volume and encapsulate tetrameric cyclic water clusters and DMF molecules. On heating to 150 8C, water and DMF are removed from the channels, which accounts for the interest of researchers in this type of compound for the preparation of inclusion compounds and sorbents. A coordination polymer with a composition similar to complex K + 7

Key indicators: single-crystal X-ray study; T = 173 K; mean (C-C) = 0.003 Å; R factor = 0.050; wR factor = 0.133; data-to-parameter ratio = 14.9.In the title compound, C 6 H 8 NO + ÁC 3 H 3 O 4 À , the amino N atom is protonated, and one of the carboxyl groups is deprotonated to maintain the charge balance. In the crystal, classical N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds connect the ions into a two-dimensional network parallel to the ac plane. In addition, the structure is further stabilized by C-HÁ Á ÁO andinteractions [centroid-centroid distance = 4.115 (2) Å ]. Related literature

An Unexpected Zinc Coordination Polymer formed during the Preparation of 5-Substituted 1H-Tetrazoles from a Nitrile in Water

Abstract: The reaction of N,N�-dicyanohydrazine with ZnCl2 and NaN3 in water unexpectedly affords 5-aminotetrazolato hydroxo zinc rather than a zinc complex with bis(tetrazolyl)hydrazine. An N–N bond cleavage has occurred in the Demko–Sharpless' tetrazole synthesis.
