Novel Lanthanide(III) Coordination Polymers with 1,4-Bis(phenyl-sulfinyl)butane Forming Unique Lamellar Square Array: Syntheses, Crystal Structures, and Properties

The syntheses, characterization, structures, and properties of a series of LnIII coordination polymers with a flexible bis(sulfinyl) ligand, 1,4-bis(phenylsulfinyl)butane (L), are reported. Unique noninterpenetrated two-dimensional (4,4) nets are formed in these complexes. The coordination number of the LnIII ions across the whole LnIII series remains unchanged, and all the complexes of this series are isomorphous and isostructural. The perchlorate anions may set as a template in the formation of these unique square arrays, and the counteranions may be a key factor in controlling the structures of such complexes.
