**3. Results and discussion**

Two different sets of complex metal hydrides have been studied in this work, one is with the mixture, 2LiBH4 + ZnCl2 with different catalysts and the other set related to destabilized materials LiBH4+ ½MgH2 + Xmol% ZnCl2 with different catalysts. The results of various physicochemical characterizations such TGA, DSC, XRD, FTIR and PCT are discussed for these two sets of complex metal hydrides in the following sub sections.
