<jats:title>Abstract</jats:title><jats:p>The new metal‐organic framework [Cd(bqdc)(phen)]<jats:italic><jats:sub>n</jats:sub></jats:italic> (<jats:bold>1</jats:bold>) (bqdc = 2, 2′‐biquinoline‐4, 4′‐dicarboxylate, phen = 1, 10‐phenanthroline) was hydrothermally synthesized by hetero‐ring carboxylate ligand and N‐containing auxiliary ligand. The structure of <jats:bold>1</jats:bold> was determined by single‐crystal X‐ray diffraction analysis and further characterized by elemental analyses, IR spectroscopy, X‐ray powder diffraction, and TG analysis. Single‐crystal X‐ray structural analysis shows that complex <jats:bold>1</jats:bold> is an infinite two‐dimensional framework containing aesthetic <jats:italic>meso</jats:italic>‐helix. These two‐dimensional coordination networks are interconnected through aromatic π–π stacking and C–H<jats:bold>···</jats:bold>O hydrogen bonding interactions to afford a 6‐connected (4<jats:sup>12</jats:sup>.6<jats:sup>3</jats:sup>) three‐dimensional supramolecular architecture. Furthermore, the photoluminescent property of complex <jats:bold>1</jats:bold> was studied.</jats:p>
