摘要

The structure of Rb-0.7(NH4)(0.3)HSO4 has been determined by X-ray analysis. The mixed compound crystallizes in the monoclinic space group P2(1) with unit cell parameters a = 14.374(6) Angstrom, b = 4.618(6) Angstrom, c = 14.412(2) Angstrom, beta = 118.03(2)degrees, V = 844.4(4) Angstrom(3), and D-cal = 1.536 g cm(-3) for Z = 8. The mixed compound Rb-0.7(NH4)(0.3)HSO4 is a chain-based structure. The Rb+ and NH4+ cations are intercalated between chains, formed of (HSO4-) groups linked with OH ... O hydrogen-bonding. Rb-0.7(NH4)(0.3)HSO4 presents a new type of structural arrangement different from those of pure RbHSO4 and NH4HSO4. [References: 19]
