derivatives could provide a satisfactory response for hydrogen production and recyclability of the formed products. To date, knowledge of the physical and chemical properties of these compounds is still scarce. In this paper, the electronic structure of various hydrazine–boranes complexes is studied by ultraviolet-photoelectron spectroscopy (UV-PES), which is the experimental technique giving direct access

diffraction pattern of the product also indicates the formation of a new crystal structure. This compound releases hydrogen at 126 and 170 °C with satisfactory purity and exhibits superior hydrogen storage properties compared with HBB. Differential scanning calorimetry measurement suggests the dehydrogenation reaction of this compound is less exothermic than that of HBB.
LiNH(BH 3)NH 2 BH 3是金属取代的肼双硼烷(HBB)的第一个实例,它是通过HBB与正丁基锂在乙醚溶液中的反应合成的。11 B NMR和傅立叶变换红外光谱表明一种新结构,其中一个N–H键被一个N–Li键取代。产物的X射线衍射图也表明形成了新的晶体结构。与HBB相比,该化合物在126和170°C下以令人满意的纯度释放氢,并显示出优异的储氢性能。差示扫描量热法测量表明该化合物的脱氢反应比HBB的放热反应少。
