| 英文摘要 | nitrogen (n) containing ligands, such as ammonia (nh3), hydrazine (n2h4), and ethylenediamine (en), can form a series of complexes with common features in crystal structures and thermal behaviors by coordinating with libh4. two newly synthesized lithium borohydride ethylenediaminates were investigated in this work. through comparing the crystal structures of libh4-en, libh4-nh3, and libh4-n2h4 complexes, similar coordination environments of li were observed in which they have the same li/n molar ratios. meanwhile, the establishment of dihydrogen bonding networks, together with the li+/n containing ligand interactions, may be important reasons for the structural stabilization and are expected to have profound impacts on their thermal behaviors. when heated under ar flow, libh4-n containing complexes decompose via desorption of n containing ligands followed by dehydrogenation. the coordination strength is affected by the number of ligands, i.e., with the increase of n/li ratio the ligands can be released more easily. for dehydrogenation, the complex with the shortest nh center dot center dot center dot hb distance gave rise to the lowest initial temperature. when heated in a closed system, direct dehydrogenation can be achieved at relatively low temperatures with co-based catalyst. about 8.5 and 7.7 wt % of hydrogen can be released from co-catalyzed libh4 center dot en and (libh4)(2)center dot en at 180 degrees c, respectively. |
