[La(UO2)V2O7][(UO2)(VO4)] the first lanthanum uranyl-vanadate with structure built from two types of sheets based upon the uranophane anion-topology

► New lanthanum uranyl vanadate divanadate has been synthesized. ► Structure was determined from single-crystal X-ray diffraction data. ► Structure is characterized by uranophane-type sheets and double layers [La(UO2)(V2O7)]+∞2.
