- Abstract
Two unique organic-inorganic hybrid polyoxometalates constructed from Preyssler-type [Na(H2O)P5W30O110]14− ({P5W30}) subunits and TM/Ln-carboxylate-Ln connectors (TM=transition metal, Ln=lanthanide), KNa7[{Sm6Mn(μ-H2O)2(OCH2COO)7(H2O)18}{Na(H2O)P5W30O110}] ⋅22 H2O ( 1) and K4[{Sm4Cu2(gly)2(ox)(H2O)24}{NaP5W30O110}]Cl2 ⋅25 H2O ( 2; gly=glycine, ox=oxalate) have been hydrothermally synthesized and characterized by elemental analyses, IR spectra, UV/Vis-NIR spectra, thermogravimetric analyses, power X-ray diffraction, and single-crystal X-ray diffraction. Compound 1 displays one interesting 3D framework built by three types of subunits, {P5W30}, [Sm2Mn(μ-H2O)2(OCH2COO)2(H2O)5]4+, and [Sm4(OCH2COO)5 (H2O)13]2+, whereas 2 also manifests the other intriguing 3D architecture created by three types of subunits, {P5W30}, [SmCu(gly)(H2O)8]4+, and [Sm2(ox)(H2O)8]4+. To our knowledge, 1 and 2 are the first 3D frameworks that contain {P5W30} units and TM/Ln-carboxylate-Ln connectors. The fluorescent properties of 1 and 2 have been investigated.
