The first structural characterization of a rare earth ethanesulfonate.
The crystal structure of catena-poly[[triaquabis(ethanesulfonato-kappaO)europium(III)]-mu-ethanesulfonato-kappa(2)O:O'], [Eu(C(2)H(5)SO(3))(3)(H(2)O)(3)](n), is the first reported determination of a rare earth ethanesulfonate and also of any hydrated binary metal ethanesulfonate. Two of the three ethanesulfonate anions act as bidentate bridging ligands and connect the single [Eu(C(2)H(5)SO(3))(3)(H(2)O)(3)] building blocks into infinite chains along the [010] direction. Hydrogen bonds between the water molecules of one chain and sulfonate anions and water molecules of adjacent chains associate the chains into a two-dimensional supramolecular network. In the third direction, only van der Waals forces between the alkyl groups are observed.
