Uranyl citrate dimers as guests in a copper–bipyridine framework: a novel heterometallic inorganic–organic hybrid compound

Abstract

Reaction of uranyl nitrate with citric acid (H4cit) in the presence of copper(II) bis(trifluoromethanesulfonate) and 4,4′-bipyridine (bipy) under hydrothermal conditions gave the mixed complex [Cu(bipy)2(H2O)2][UO2(Hcit)(H2O)]2·5H2O, in which dianionic uranyl citrate dimers are incorporated in the interlayer spaces of the [Cu(bipy)2(H2O)2]n2n+ square grid assemblage. An extended hydrogen bonding network links the uranyl complex units together and also to the grid framework, resulting in the formation of a 3-D assemblage held by weak interactions.
