摘　　要：AlH_(3)是一种新兴的含能材料,与Al粉相比,具有更高的能量密度。同时AlH_(3)燃烧释放大量的氢气,能显著降低燃气平均分子量,可以用作火炸药的含能组分。但AlH_(3)转晶过程极为危险,不稳定杂相分离困难,难以获得纯净的稳定相α‑AlH_(3)。制备AlH_(3)配合物则可规避转晶的危险性,同时配合物保持了AlH_(3)的结构单元,可以通过重结晶方法进行纯化,具有广阔的应用前景。本文综述了AlH_(3)配合物的合成方法、AlH3配合物的配位模式以及AlH_(3)配合物的种类及应用,重点分析了叔胺、叔膦、醚和卡宾配体及不同配位结构对AlH_(3)配合物的热化学性能的影响,展望了AlH_(3)配合物的研究方向。Aluminum hydride(AlH3)is a new energetic material with higher energy density than aluminum.A large amount of hydrogen produced in the combustion of AlH_(3),which significantly reduced the average molecular weight of gas products.AlH3 can be used as an energetic component of explosives.However,the crystal transformation process of AlH3 is extremely dangerous and the unstable impurity phase is difficult to separate,thus it is challenge to obtain the pure stable phaseα‑AlH_(3).The preparation of AlH_(3)complexes can avoid the danger of crystal transformation of AlH_(3),AlH_(3)complexes retain the structural unit of AlH_(3),avoid the dangerous crystal transformation process,and can be purified by recrystallization,which has a broad application prospect.This paper reviews the synthesis methods,coordination modes,types and applications of AlH_(3)complexes,and focuses on the effects of different ligands,such as tertiary amine,tertiary phosphine,ether and carbene,and different coordination structures on the thermochemical properties of AlH3 complexes.The future research direction of AlH3 complexes is clarified.
