摘要：
The action of dimethylformamide on diaqua(benzoato)chlorodioxouranium(VI), in the presence of beta-cyclodextrin, yields the title compound. The crystal structure of this new complex reveals that the linear uranyl is equatorially surrounded by five O atoms, one from a dmf molecule, two from a bidentate benzoate anion and one each from two separate bridging benzoate ligands, shared by the U atoms forming a neutral dimeric entity. The average U-O distance involving the bridging benzoates [2.31 (1) angstrom] is significantly shorter than that involving the other benzoates [2.44 (2) angstrom].
