Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Zeitschrift fuer Anorganische und Allgemeine Chemie called Direct Synthesis and Characterization of New Copper(II) and Zinc(II) 5-R-Tetrazolato Complexes [R = Me, Ph, 4-Py] with Ethylenediamine and DMSO as Coligands, Author is Mosalkova, Anastasiya P.; Voitekhovich, Sergei V.; Lyakhov, Alexander S.; Ivashkevich, Ludmila S.; Gaponik, Pavel N.; Ivashkevich, Oleg A., which mentions a compound: 14389-12-9, SMILESS is C1(C2=NN=NN2)=CC=NC=C1, Molecular C6H5N5, Application In Synthesis of 5-(4-Pyridyl)-1H-tetrazole.
Three novel 5-R-tetrazolato complexes (R = Me, Ph, 4-Py), [Zn2(MeCN4)4(DMSO)2]n (1), [Cu2(PhCN4)4(en)2]·2DMSO (2), and {[Cu(4-PyCN4)2(DMSO)2]·4DMSO}n (3), were isolated as unexpected products under attempts to prepare heterometallic tetrazolates using a direct synthesis strategy in the Cu0-ZnO-en-RCN4H-DMSO system (en = ethylenediamine). The prepared compounds were characterized by elemental, single-crystal x-ray, and thermal analyses, and IR spectroscopy. Variation of the 5-substituent of the tetrazole ring causes different composition of complexes 1-3 and diverse coordination modes of 5-R-tetrazolato ligands. Complex 1 is a 3-dimensional coordination polymer due to N1,N4-bridging of 5-methyltetrazolato anions. Complex 2, with en as a coligand, has a dinuclear structure with two copper atoms linked together by two 5-phenyltetrazolato ligands by tetrazole N2,N3 bridges. Complex 3 represents a 2-dimensional coordination polymer, formed due to 5-(4-pyridyl)tetrazolato bridges between adjacent copper atoms (with the tetrazole and pyridine rings nitrogen atoms as coordination centers). DMSO mols., included in all the compounds, are solvate and/or coordinated ones.
