| الوصف: | Two new scandium-containing coordination polymers, with the formulae {(CH3)2NH2}[Sc(BPDC)2] (1) and [Sc(OH) (BPyDC)] (2) were solvothermally synthesized by using the linear linker molecules biphenyl-4,4′-dicarboxylic acid (H2BPDC) and 2,2′-bipyridine-5,5′-dicarboxylic acid (H2BPyDC). Crystal structures were determined from single-crystal and powder Xray diffraction data, respectively. The crystal structures of 1 and 2 contain isolated ScO6 or chains of trans corner-sharing ScO6 octahedra as the inorganic building unit (IBU), which are connected by the linker molecules to a 3D framework or a layered structure, respectively. The compounds were characterized by IR-spectroscopy, elemental analysis, thermogravimetric analysis and photoluminescence spectroscopy. 1 shows blue emission at 400 nm, while 2 exhibits intense green emission at 550 nm with a high quantum yield (QY) of 69 %. |
