Poly[aqua­(μ5-2-oxido-4-sulfonato­benzoato)lanthanum(III)]

The title compound, [La(C7H3O6S)(H2O)]n, forms a three-dimensional framework in which the asymmetric unit contains one LaIII atom, one 5-sulfosalicylate (2-oxido-4-sulfonatobenzoate) ligand and one coordinated water mol­ecule. The LaIII atom is coordinated by nine O atoms from three carboxyl­ate, three sulfonate and two hydroxyl groups, and one water mol­ecule, forming a distorted trigonal-prismatic square-face tricapped geometry

Experimental and Theoretical Evidence for the First Example of an Organolanthanide(II) Compound Having an Indenyl Ligand Bonded to the Metal through the Benzo Ring in η4 Hapticity

International audienceThe reaction of 2 equiv of C9H6-1-SiMe3-3-CH2CH2NC5H10 (2) with the ytterbium(III) amide [(Me3Si)2N]3Yb-(μ-Cl)Li(THF)3 produced a novel ytterbium(II) complex with an indenyl ligand bonded to the metal via the benzo ring with η4 hapticity, [η4:η2:η1-(C5H10NCH2CH2C9H5SiMe3)Li(μ-Cl)]Yb-(η5:η1-C5H10NCH2CH2C9H5SiMe3) (1), as verified by a solid-state structure determination and theoretical calculations
