The crystal structures of three sulfonato complexes of uranyl ion are described. All have linear UO2 groups pentagonally coordinated by sulfonato or aquo ligands. In [(UO2)(H2O)(EtSO3)2] the coordination about UO2 is provided by four O donated by two EtSO3- ligands and one O by water: a sulfonate group links the pentagonal bipyramids into chains propagating along the a axis. p-Toluenesulfonato and mesitylenesulfonato complexes of uranyl ion are monomeric and in each complex two O are donated by monodentate sulfonate and three O by water molecules. The tendencies for complexes with small ligands to form polymeric structures, and for those with bulky ligands to give monomeric structures, which we have observed with carboxylate ligands, seem to extend to sulfonate ligands.
