Abstract

A new organically templated uranyl molybdate [C3H9NH+](4)[(UO2)(3)(MoO4)(5)] was prepared by a hydrothermal method at 220 degrees C. The compound is monoclinic,Cc,a= 16.768(6),b= 20.553(8),c= 11.897(4) angstrom, beta = 108.195(7),V= 3895(2) angstrom(3),R-1= 0.05. The crystal structure is based upon [(UO2)(3)(MoO4)(5)](4-)uranyl molybdate layers. The isopropylammonium cations are located in the interlayer. The layers in the structure of [C3H9NH+](4)[(UO2)(3)(MoO4)(5)] are considered as modular architectures. Topological analysis of layers with UO2:TO(4)ratio of 3:5 (T-VI= S, Cr, Se, Mo) was performed. Modular description is employed to elucidate the relationships between different structural topologies of [(UO2)(3)(TO4)(5)](4-)layers and inorganic uranyl-based nanotubules. The possible existence of uranyl molybdate nanotubules is discussed.
