Photosensitive Metal(II) Perchlorates with 1,2‐Bis[5‐(1‐methylhydrazinyl)tetrazol‐1‐yl]ethane as Ligand: Synthesis, Characterization and Laser Ignition

This is the authors' abstract. We don't add key points for this paper.

The synthesis and characterization (including NMR spectroscopy, elemental analysis, X‐ray diffraction, infrared spectroscopy and sensitivity measurements) of 1,2‐bis[5‐(1‐methylhydrazinyl)tetrazol‐1‐yl]ethane (1) and its corresponding metal [Cu2+ (2), Co2+ (3), Ni2+ (4)] complexes is presented. The crystal structure of the copper(II) complex was determined and infrared spectra of all three coordination compounds were recorded. Furthermore, the behaviour of the metal(II) complexes towards single‐pulsed laser irradiation was investigated and it was shown that all three perchlorate complexes detonated after initiation by monopulsed laser light. The initiation mechanism seems to be of thermal nature.
