Development of condensed energetic systems, especially photosensitive primary explosives for the systems of laser initiation is one of the foremost fields of application of energetic materials. There have been synthesized and investigated a coordination complex of mercury(II) chlorate(VII) with 5-hydrazinotetrazole as ligand (compound (I)) as a potential photosensitive primary explosive. This complex consisting of particles of 1.1 0.8 m size demonstrated the highest sensitivity to laser irradiation combined with an extremely low initiation threshold. On the basis of compound (I) a photosensitive formulation EC-2 containing ∼ 90% of the complex mercury(II) chlorate(VII) and ∼ 10% of an optically transparent polymer as an inert matrix has been proposed. Formulation EC-2 has extremely high sensitivity to Q-switch IR-laser irradiation. Formulation EC-2 with added ultra disperse diamonds (UDD) has shown lower initiation thresholds in comparison with neat EC-2 or EC-2 with added submicron black carbon, fullerens or nanotubes instead of UDD.
