| description | In order to explore the effect of the energetic complex on the thermal decomposition HMX, two new rare-earth energetic complexes [La(tza)(NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]<i><sub>n</sub></i> (<b>1</b>) and [Ce(tza)(NO<sub>3</sub>)<sub>2</sub>(H<sub>2</sub>O)<sub>4</sub>]<i><sub>n</sub></i> (<b>2</b>) (Htza = tetrazole-1-acetic acid) were prepared by a solvent evaporation method. The obtained products were structurally characterized by Fourier-transform infrared spectroscopy (FTIR), elemental analysis, powder X-ray diffraction (PXRD), single crystal X-ray diffraction (XRD), and thermogravimetric analysis coupled with differential scanning calorimetry (TG-DSC). In addition, the compatibility of complex <b>1</b> with cyclotetramethylene tetranitramine (HMX) was studied by DSC and FTIR, respectively. Structural analysis suggested that complex <b>1</b> exhibits an orthorhombic, P 2<sub>1</sub> 2<sub>1</sub> 2<sub>1</sub> space group, and the La (III) ion was 10-fold coordinated in a distorted double-capped antiprism configuration. Complex <b>2</b> featured a one-dimensional, right-handed helical infinite chain. The effect of complexes <b>1</b> and <b>2</b> on the thermal decomposition of HMX was investigated by DSC, which revealed that complex <b>1</b> showed a slightly better effect than <b>2</b> on the thermal decomposition of HMX and released more heat. Furthermore, complex <b>1</b> had good compatibility with HMX, indicating that it may act as a combustion promoter for nitrate ester plasticized polyether (NEPE) solid propellant. |
