Crystal structures and luminescent properties of a cadmium(II) metal-organic framework based on tri(4-pyridylphenyl)amine LiJun-Feng XuXiu-Dian ZhouZe-Yu ChenLi-Zhuang WangFang-Ming 2018 <p>A luminescent cadmium(II) metal-organic framework, [Cd(tppa)<sub>2</sub> (bpdc)<sub>2</sub>]<i><sub>n</sub></i> (<b>1</b>) (tppa = tri(4-pyridylphenyl)amine, bpdc =4,4′-biphenyldicarboxylic acid), has been solvothermally synthesized by using Cd(NO<sub>3</sub>)<sub>2</sub>·4H<sub>2</sub>O and a mixture of tppa and bpdc. Single crystal X-ray analysis reveals that <b>1</b> crystallizes in the orthorhombic system and <i>Pbcn</i> space group. Its overall structure is a twofold interpenetrated framework, and it shows a porosity of 31.8% based on a calculation by PLATON and a 4-<i>c</i> type topological network with the point symbol of {6^5.8}. In addition, <b>1</b> may be exploited as WLED due to its ability to give off yellow light under ultraviolet excitation.</p>
