Abstract

The first example of a mixed-metal amidoborane Na(2)Mg(NH(2)BH(3))(4) has been successfully synthesized. It forms an ordered arrangement in cation coordinations, i.e., Mg(2+) bonds solely to N(-) and Na(+) coordinates only with BH(3). Compared to ammonia borane and monometallic amidoboranes, Na(2)Mg(NH(2)BH(3))(4) can release 8.4 wt% pure hydrogen with significantly less toxic gases.

摘要

首例混合金属氨硼烷 Na(2)Mg(NH(2)BH(3))(4) 已成功合成。它在阳离子配位中形成有序排列，即 Mg(2+) 仅与 N(-) 键合，而 Na(+) 仅与 BH(3) 配位。与氨硼烷和单金属氨硼烷相比，Na(2)Mg(NH(2)BH(3))(4) 可释放出 8.4wt%的纯氢，且毒性气体明显较少。
