摘要: In this work, a series of Mn-based borohydrides were synthesized by mechanochemical milling ABH\(_4\)-MnCl\(_2\) (where A=Li, Na, K) under argon. Samples prepared xLiBH\(_4\)-MnCl\(_2\) x = 2 or 3) resulted in the formation Mn(BH\(_4\))\(_2\) and LiCl stoichiometric ratio. Thermal decomposition was observed between 105 180°C with concurrent evolution hydrogen diborane. Analysis products suggested presence amorphous B, Mn LiCl. When NaBH\(_4\) used as reagent, also observed, however instead NaCl, solid solution NaCl\(_x\)(BH\(_4\))\(_1\)\(_-\)\(_x\) Na\(_6\)MnCl\(_8\) formed. decomposed 110 170°C for xNaBH\(_4\)-MnCl\(_2\) samples showed that B formed (110 to 170°C) reacted Na\(6\)MnCl\(_8\) produce NaCl (250 475°C). When KBH\(_4\) not observed. Rather, K\(_2\)Mn(BH\(_4\))\(_4\), KMnCl\(_3\) unreacted The mass losses milled sample 100 160°C release trace diborane, forming KBH\(_4\), Mn, 165 260°C only release, giving KCl, Mn.
