Rubidium iron bis-[hydrogen arsenate(V)], RbFe(HAsO), and thallium iron bis-[hydrogen arsenate(V)], TlFe(HAsO), were grown under mild hydro-thermal conditions ( = 493 K, 7 d). RbFe(HAsO) adopts the RbFe(HPO) structure type (space group ), while TlFe(HAsO) crystallizes in the (NH)Fe(HPO) structure type (space group ). Both compounds have tetra-hedral-octa-hedral framework topologies. The cations are located in channels of the respective framework and are disordered in TlFe(HAsO), which may suggest that the cations can move in the channels.
铷铁双[砷酸氢（V）]，RbFe(HAsO₄)，和铊铁双[砷酸氢（V）]，TlFe(HAsO₄)，在温和水热条件下（493 K，7天）生长。RbFe(HAsO₄)采用RbFe(HPO₄)结构类型（空间群），而TlFe(HAsO₄)以(NH₄)Fe(HPO₄)结构类型结晶（空间群）。两种化合物都具有四面体-八面体框架拓扑结构。阳离子位于各自框架的通道中，并且在TlFe(HAsO₄)中无序，这可能表明阳离子可以在通道中移动。
