Low-frequency resonance technology is a promising technology for mixing or manufacturing energetic materials, and has been a hot topic in the field of material preparation. In this paper, we describe the first use of low-frequency resonance technology for the synthesis of new compounds and for performing innovative research. The coordination compound, [K(18-crown-6)][N(NO2)2] ([K(18C6)][N(NO2)2]), was first prepared by using a conventional slow solvent evaporation method over 10 days. The crystal structure of this compound was characterized by single crystal X-ray diffraction (SXD) and revealed that [K(18C6)][N(NO2)2] belongs to the monoclinic system, in which the space group is P21/c. The main intermolecular interactions in [K(18C6)][N(NO2)2] are the K–O coordination bonds and C–H...O hydrogen bonds. The crystallographic parameters are a = 8.5032(2) Å, b = 14.4060(4) Å, c = 8.1708(2) Å, β = 101.896(2), V = 979.40(4) Å3, Z = 2, ρ = 1.388 g·cm–3. The coordination compound [K(18C6)][N(NO2)2] was then prepared by low-frequency resonance technology in only 65 min. The results of X-ray powder diffraction (PXRD), differential scanning calorimetry (DSC) and infrared spectroscopy (FTIR) showed that low-frequency resonance technology can successfully and efficiently prepare [K(18C6)] [N(NO2)2]. Compared to potassium dinitramide (KDN), [K(18C6)][N(NO2)2] has unique characteristics.
