- Abstract
Rubidium iron bis[hydrogen arsenate(V)], RbFe(HAsO4)2, and thallium iron bis[hydrogen arsenate(V)], TlFe(HAsO4)2, were grown under mild hydrothermal conditions (T = 493 K, 7 d). RbFe(HAsO4)2 adopts the RbFe(HPO4)2 structure type (space group R3c), while TlFe(HAsO4)2 crystallizes in the (NH4)Fe(HPO4)2 structure type (space group P1). Both compounds have tetrahedral-octahedral framework topologies. The M+ cations are located in channels of the respective framework and are disordered in TlFe(HAsO4)2, which may suggest that the M+ cations can move in the channels.
