英文摘要	interaction of [bhx] and [nhx] species gives rise of molecular hydrogen and the set-up of b-n bond. metal amides and ammonia are the commonly used [nhx] sources. herein, urea (co(nh2)(2)), an organic carbonyl diamide, was applied to react with libh4. a new type of complex hydrides libh4 center dot co(nh2)(2), was synthesized by ball milling libh4 and co(nh2)(2) in a molar ratio of 1:1 in this work. structural analyses show that this newly developed complex has a monoclinic structure (space group c12/c1) with unit-cell parameters of a = 14.629(2) angstrom, b = 5.8701(11) angstrom, c = 13.662(3) angstrom, beta = 115.135(7)degrees, and v = 1062.1(3) angstrom(3), in which li+ coordinates with two [bh(4)1(-) groups and two o atoms of two co(nh2)(2) molecules. the dehydrogenation properties of libh4 center dot co(nh2)(2) were subsequently measured, and ca. 8.13 wt% of h-2 can be released exothermically at temperatures below 250 degrees c. copyright (c) 2014, hydrogen energy publications, llc. published by elsevier ltd. all rights reserved.
