ABSTRACT: N1-substituted tetrazoles are interesting ligands in transition metal coordination chemistry, especially in the field of spin crossover. Their synthesis is performed in most cases according to the Franke-synthesis, using a primary amine as reagent introducing the substitution pattern. To enhance flexibility in means of substrate scope, we developed a new protocol based on alkylation of lithium

synthetic route toward newcopper(II) chlorate complexes with potential use in modern advanced ignition or initiation systems is described. Obtained compounds were not only accurately characterized (XRD, IR, UV/Vis EA and DTA) but also investigated for their energetic character (sensitivities, initiation capability and laser ignition). The copper 4-aminotriazolyl chlorate complex showed excellent initiation
描述了一种在现代先进点火或引发系统中具有潜在用途的新型氯酸铜 (II) 复合物的便捷合成路线。获得的化合物不仅被准确表征(XRD、IR、UV/Vis EA 和 DTA),而且还研究了它们的能量特性(灵敏度、引发能力和激光点火)。4-氨基三唑基氯酸铜配合物显示出优异的PETN引发,同时还具有热稳定性和安全性。进行了固态 UV-Vis 测量,以获得对激光引发机制的可能见解。In contrast to expectations, the presented copper(II) chlorate energetic coordination compounds show manageable sensitivities that can be tamed or boosted by the appropriate choice of nitrogen-rich ligands.

of the latter shows two symmetry-related, interpenetrating Fe–btzb networks in which the iron(II) ions approach each other as close as 8.3 and 9.1 Å. This supramolecular catenane undergoes a sharp thermal spintransition around 160 K with hysteresis (20 K) along with a pronounced thermochromic effect. The spin crossover behaviour has been followed by magnetic, DSC, optical spectroscopy and 57Fe Mössbauer

A thorough investigation into the role of the counterion and occluded solvent on the structure and spin-crossover behaviour of the threefold interpenetrated network [Fe(4ditz)(3)](2+) [4ditz = 1,4-bis(tetrazol-1-yl) butane I is presented. As seen by X-ray single crystal diffraction, changing the hexafluorophosphate anion in the previously investigated trigonal phase [Fe(4ditz)(3)](PF6)(2) to tetrafluoroborate
