چکیده
In the title compound, 2C6H11N2 (+)·P2Se8 (2-) or [EMIM]2P2Se8 (EMIM = 1-ethyl-3-methyl-imidazolium), the anions, located about inversion centers between EMIM cations, exhibit a cyclo-hexane-like chair conformation. The cations are found in columns along the a axis, with centroid-centroid distances of 3.8399 (3) and 4.7530 (2) Å. The observed P-Se distances and Se-P-Se angles agree with other salts of this anion.

The nitration pattern of energetic 3,6-diamino-1,2,4,5-tetrazine derivatives containing azole functional groups.
One of the successful strategies for the design of promising new energetic materials is the incorporation of both fuel and oxidizer moieties into the same molecule. Therefore, during recent years, synthesis of various nitro-azole derivatives, as compounds with a more balanced oxygen content, has become very popular. In the framework of this effort, we studied nitration of N(3),N(6)-bis(1H-tetra...
