A practical and brilliant way of preparing laser energetic coordination polymers based on crystallization chemistry and coordination theory is proposed in this paper. Design and successful synthesis of urazine (CHNO, Hur, ) by the theory of "cyclization of semicarbazides" are reported. Using the "acid-controlled self-crystallization" synthesis method, with Hur as the ligand, we successfully synthesized [Ag(Hur)ClO·HO] () and confirmed its composition and 1D structure. In addition, was subjected to a simple drying operation to obtain a solvent-free [Ag(Hur)ClO] (). Also, has the best abilities in physics and chemistry, such as excellent thermal stability, insensitivity to light, mechanical insensitivity, and good corrosion resistance. In particular, thermogravimetric analysis-differential scanning calorimetry-Fourier transform infrared spectroscopy and powder X-ray diffraction were employed to analyze the thermal decomposition products of and demonstrated that the main decomposed products are AgCl, N, and HO. Moreover, the calculated predictions show that has an acceptable detonation performance ( = 22.5 GPa; = 6.9 km s). Furthermore, the hot needle examination and detonation experiment show that can be used as a primary explosive. More importantly, as a laser-detonated light-sensitive material, has a significant application value in safety detonators ( = 100 mJ, = 10 W, and τ = 10 ms).
