The invention belongs to the technical field of chemical synthesis, and particularly relates to a synthesis method of an alkali metal aluminum coordination hydride. The method comprises the following steps: mixing two or three of metal potassium, metal aluminum, sodium hydride and lithium hydride, and carrying out ball milling in a hydrogen atmosphere for 6-72 hours to prepare the alkali metal aluminum coordination hydride. Compared with the existing synthesis method under high temperature and high pressure, the method provided by the invention has the advantages of no use of organic solvent for purification, simple synthesis process, mild reaction conditions, high product purity, high yield, low cost, environmental friendliness, high safety coefficient and convenience in large-scale production. The synthesis method of the alkali metal aluminum coordination hydride is a green, novel, efficient and low-cost synthesis method. 本发明专利属于化学合成技术领域，具体涉及一种碱金属铝配位氢化物的合成方法。本发明方法是将金属钾、金属铝、氢化钠、氢化锂中的两种或三种混合，在氢气的氛围下球磨6-72小时便可
