N2 - Two unique organic-inorganic hybrid polyoxometalates constructed from Preyssler-type [Na(H2O)P5W30O 110]14- ({P5W30}) subunits and TM/Ln-carboxylate-Ln connectors (TM=transition metal, Ln=lanthanide), KNa 7[{Sm6Mn(μ-H2O)2(OCH 2COO)7(H2O)18}{Na(H 2O)P5W30O110}]×22 H 2O (1) and K4[{Sm4Cu2(gly) 2(ox)(H2O)24}{NaP5W 30O110}]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-H 2O)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, {P 5W30}, [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. Now in 3D! The first {P5W30}-based transition-metal (TM)-Ln heterometallic clusters exhibit unprecedented 3D frameworks that consist of {P5W30} subunits and TM/Ln-carboxylate-Ln connectors (see figure).
