英文摘要 | a new type of hydrogen storage material namely, calcium borohydride diammoniate (ca(bh4)(2)center dot 2nh(3)), is synthesized by reacting calcium borohydride and 2 equiv of ammonia. structural analyses show that this complex has an orthorhombic structure (space group pbcn) with unit-cell parameters of a = 6.4160 angstrom, b = 8.3900 angstrom, c = 12.7020 angstrom, and v = 683.75 angstrom(3), in which ca2+ coordinates with four -bh4 groups two -nh3 groups. the presence of nh3 in the crystal lattice facilitates the formation of b-h center dot center dot center dot h-n dihydrogen bonding. as a consequence, the bond lengths of b-h and n-h arc increased with comparison to ca(bh4)(2) and nh3, respectively. our experimental results show that more than 11.3 wt % hydrogen can be released exothermically from ca(bh4)(2)center dot 2nh(3) in a closed vessel at a temperature as low as 250 degrees c. |
