The material described by NaRbH2 crystallizes in the tetragonal P4/mmm space group. The structure consists of one 7440-23-5 atom inside a RbH2 framework. In the RbH2 framework, Rb(1) is bonded to two equivalent H(2) and four equivalent H(1) atoms to form a mixture of corner and edge-sharing RbH6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent H sites. In the first H site, H(1) is bonded in a square co-planar geometry to four equivalent Rb(1) atoms. In the second H site, H(2) is bonded in a linear geometry to two equivalent Rb(1) atoms. is represented by the CIF file [CIF]
