Abstract

<jats:p>Two new scandium‐containing coordination polymers, with the formulae {(CH<jats:sub>3</jats:sub>)<jats:sub>2</jats:sub>NH<jats:sub>2</jats:sub>}[Sc(BPDC)<jats:sub>2</jats:sub>] (<jats:bold>1</jats:bold>) and [Sc(OH) (BPyDC)] (<jats:bold>2</jats:bold>) were solvothermally synthesized by using the linear linker molecules biphenyl‐4,4'‐dicarboxylic acid (H<jats:sub>2</jats:sub>BPDC) and 2,2'‐bipyridine‐5,5'‐dicarboxylic acid (H<jats:sub>2</jats:sub>BPyDC). Crystal structures were determined from single‐crystal and powder X‐ray diffraction data, respectively. The crystal structures of <jats:bold>1</jats:bold> and <jats:bold>2</jats:bold> contain isolated ScO<jats:sub>6</jats:sub> or chains of <jats:italic>trans</jats:italic> corner‐sharing ScO<jats:sub>6</jats:sub> 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. <jats:bold>1</jats:bold> shows blue emission at 400 nm, while <jats:bold>2</jats:bold> exhibits intense green emission at 550 nm with a high quantum yield (QY) of 69 %.</jats:p>
