Abstract
CL-20 or HNIW is a novel, caged-type explosive material having six nitramine groups. In the present study, interaction of CL-20 with zinc atom has been investigated within the constraints of density functional theory at the level of B3LYP/6-31+G(d,p). Zinc, in chemistry is known as a good reducing metal for many functional groups, presently not only reduces one of the nitro groups but also causes cleavage of one of the nitramine bond (from the base ring) and the C-N bond of the cage. The zinc atom acquires some positive charge after all.
