The crystal structure of a mixed amide-imide phase, RbMgND2ND, has been solved in the orthorhombic space group Pnma (a = 9.55256(31), b = 3.70772(11) and c = 10.08308(32) Å). A new metal amide-hydride solid solution, Rb(NH2)xH(1–x), has been isolated and characterized in the entire compositional range. The profound analogies, as well as the subtle differences, with the crystal chemistry of KMgND2ND
已在正交空间群Pnma(a = 9.55256(31),b = 3.70772(11)和c = 10.08308(32)Å)中解决了酰胺-酰亚胺混合相RbMgND 2 ND的晶体结构问题。一种新的金属酰胺氢化物固溶体Rb(NH 2)x H (1- x)已被分离出来,并在整个组成范围内进行了表征。KMgND 2 ND和K(NH 2)x H 1– x的晶体化学具有深远的类比和细微的差异进行了彻底的讨论。这种方法表明,使用K-和为Mg系的Rb-添加剂(NH获得的可比较的性能2)2 -2LiH和2LiNH 2 -MgH 2储氢系统可能依赖于可能的反应产物和中间体的结构相似。
