English abstract:
The crystal structures of hydrothermally synthesized (T = 493 K, 7-9 d)
ammonium gallium bis[hydrogen arsenate(V)], (NH4)Ga(HAsO4)2 , and thallium
aluminium bis[hydrogen arsenate(V)], TlAl(HAsO4)2 , were solved by
single-crystal X-ray diffraction. Both compounds crystallize in the common
RbFe(HPO4)2 structure type (R-3c) and share the same tetrahedral-octahedral
framework topology that houses the M+ cations in its channels. One of the two
Tl sites is slightly offset from its ideal position. Strong O-H...O hydrogen
bonds strengthen the network.
Keywords:
