摘要

A series of 12 inorganic–organic hybrid 4 f ‐substituted arsenotungstates decorated with 3 d ‐based complexes along with acetate bridging, viz. {[Cu 2 (H 2 O)(1,10‐phen) 2 (μ‐CH 3 COO) 2 ] 4 [Ln 2 (H 2 O) 2 (μ‐CH 3 COO) 2 (α‐AsW 11 O 39 ) 2 ]} 2? (Ln III = Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu), have been synthesized. These compounds were isolated using a one‐pot synthetic strategy with copper, lanthanoid, trilacunary arsenotungstate and 1,10‐phenanthroline as precursors. They were characterized using various analytical techniques, such as single‐crystal X‐ray diffraction (SC‐XRD), powder XRD (PXRD), Fourier transform IR (FT–IR) spectroscopy, UV–Vis spectroscopy and thermogravimetric analysis (TGA). In all these compounds, a dinuclear Ln 2 (ac) 2 moiety is sandwiched between two monolacunary [AsW 11 O 39 ] 7? polyoxometalates (POMs), where the Ln 2 (ac) 2 moiety is comprised of two acetate ligands in a μ‐κ O , O ′:κ O fashion. Moreover, the anion is decorated by a copper–phenanthroline–acetate complex through a terminal O atom of the polyanion.
