Description | ||||||
Structural analyses of [Rbx(NH4)1_x]3H(SO4)2 for x = 0.14, 0.33 and 0.50 (TRAHS) single crystals are performed by X-ray diffraction experiments in order to investigate the hydrogen bond (H-bond) connection in (S0 4·H·...SO4'') dimers. The H-bond length Ro-o is determined from the model for H-bond attached to oxygen atoms. In the study, hydrogen bonding is realised with Ro-o distance being 2.549 Ain (NH4)3H (SO4)2 and 2.492 Å in Rb3H(SO4)2.The H-bond length Ro-o of TRAHS varies with x and is less than that obtained for pure crystals. The values with x = 0.14, 0.33 and 0.50 are 2.449, 2.522 and 2.515 A, respectively. These are close to but still longer than the so-called critical bond length Rc• The observed lattice parameters vary systematically with x showing that the mixed crystals are solid solution of two analogues. All these crystals are monoclinic with the space group C2/c and Z = 4. | ||||||
