| 英文摘要 | a stepwise phase transition in the formation of lithium amidoborane via the solid-state reaction of lithium hydride and ammonia borane has been identified and investigated structural analyses reveal that a lithium amidoborane-ammonia borane complex (linh(2)bh(3)center dot nh(3)bh(3)) and two allotropes of lithium amidoborane (denoted as alpha- and beta-linh(2)bh(3), both of which adopt orthorhombic symmetry) were formed in the process of synthesis linh(2)bh(3)center dot nh(3)bh(3) is the intermediate of the synthesis and adopts a monoclinic structure that features layered linh(2)bh(3) and nh(3)bh(3) molecules and contains both ionic and dihydrogen bonds unlike alpha-linh(2)bh(3), the units of the beta phase have two distinct li(+) and [nh(2)bh(3)](-) environments. beta-linh(2)bh(3) can only be observed in energetic ball milling and transforms to alpha-linh(2)bh(3) upon extended milling. both allotropes of linh(2)bh(3) exhibit similar thermal decomposition behavior, with 10.8 wt % h(2) released when heated to 180 degrees c; in contrast, linh(2)bh(3)center dot nh(3)bh(3) releases approximately 14.3 wt % h(2) under the same conditions |
