摘要：

A synthesis and purification method for Mg(AlH4)(2) is presented, which is based on a metathesis reaction of NaAlH4 and MgCl2 in diethyl ether and subsequent purification procedure leading to a high yield of the monoether adduct of Mg(AlH4)(2). After removal of the solvent, the alanate has been obtained as a nanocrystalline material with a yield of 81% and a purity of 95%. Crystal structures were determined and discussed for the solvent adducts Mg(AlH4)(2).4THF and Mg(AIH(4))(2).Et2O. A proposition is made for the structure of Mg(AIH(4))(2).
