金属硼氮氢化合物（MBNH）是一种典型的以富氢B-N为特征的固体储氢材料，由于其高储氢容量和可调储氢性能，近十年来发展非常迅速，如金属氨基硼烷（M(NH2NH2BH3)n， MAB）、金属肼硼烷（M(NH2NH2BH3)n， MHB）、胺金属硼氢化物（M(BH4)n·mNH3， AMB）及其衍生物。MAB是用一种轻金属阳离子（一般为碱或碱土金属）取代AB （NH3BH3）的氢阳离子得到的，这是近15年来著名的储氢材料。MHB是由轻金属取代H(N)原子形成的，这与MAB类似。AMB是由金属硼氢化物与氨反应合成的。近十年来制备了大量不同金属或不同NH3配位数的AMBs。在这一领域，所有的化合物都含有强的路易斯酸/碱相互作用（如B-N相互作用）。氢由Hδ+···Hδ−的二氢键生成，金属作为可控的氢载体，在脱氢过程中提高了产品的纯度。本文综述了新型固体MBNH化合物MAB、MHB和AMB的合成方法、结构和脱氢性能。我们希望这一综述能够为开发具有先进储氢性能的新型MBNH化合物提供更广泛的研究。
Metal boron-nitrogen-hydrogen (MBNH) compound is a kind of typical solid hydrogen storage material characterized by hydrogen-rich B-N species, which has been developed very fast in the last decade due to its high hydrogen capacity and the tunable hydrogen storage properties, such as metal amidoborane (M(NH2BH3)n, MAB), metal hydrazinidoborane (M(NH2NH2BH3)n, MHB), amine metal borohydride (M(BH4)n· mNH3, AMB) and their derivatives. MAB is obtained by replacing a hydrogen cation of AB (NH3BH3) by a light metal cation (such as the alkali or alkali earth metal, generally), which was a famous hydrogen-storage material in last 15 years. MHB is formed by replacing a H(N) atom with light metal, which is similar with that of MAB. AMB is synthesized by the reaction between metal borohydrides and ammonia. There are a large amount of AMBs prepared in the recent ten years with different metals or different coordination numbers of NH3. In this field, all the compounds are containing a strong Lewis acid/base interaction (such as B-N interaction). Hydrogen is generated from the dihydrogen bond of Hδ+··· Hδ−, where the metal works as a controllable hydrogen carrier to improve the purity of product in the dehydrogenation process. In this review, we focus on the novel solid MBNH compounds including MAB, MHB and AMB with their synthesis methods, structures and dehydrogenation properties. We hope this review can enlighten more extensive studies for the development of new MBNH compounds with advanced hydrogen storage performances.
