摘要:

A three-dimensional (3D) 3d-4f complex, [Cu(en)2][Sm2(C5O5)(C2O4)3(H2O)2]·8H2O (1) (en = ethylenediamine, C5O52– = dianion of 4,5-dihydroxycyclopent-4-ene-1,2,3-trione), were prepared via the in-situ ring-opening oxidation reaction of croconate in the presence of the template-directed complex, [Cu(en)2]2+ cation. The structural characterization determined by X-ray diffraction determination reveals that the 3D anionic coordination polymer of [Sm2(C2O4)3(C5O5)(H2O)2]2– in 1 can be describe in terms of in-plane 2D honeycomb-like [Sm2(C2O4)3] layered frameworks bridged by oxalate with bis-chelating mode, being mutually interlinked via the bridge of μ1,2,3,4-croconate ligands with bis-chelating coordination mode to complete the 3D open framework, which gives rise to 1D channels with pore size of 14.023×11.893 Å angstrom (longest atom-atom contact distances) along the b axis. The structure-directing complex, [Cu(en)2]2+, and solvated water molecules are resided into these honeycomb-type hexagonal channels. The thermal stability of 1 was further studied by TGA and in-situ powder X-ray diffraction measurement.
