Two coordination polymers (CPs), namely, [Cu(Hptz) 2 (Hhba) 2 ] n ( 1 ) [Hptz = 5‐(4‐pyridyl)‐1H‐tetrazole, H 2 hba = 2‐hydroxybenzoic acid] and [Zn 3 (ptz) 2 (hpa) 2 ] n ( 2 ) (H2hpa = 2‐hydroxy‐2‐phenylacetic acid), were synthesized by solvothermal reactions. Both complexes were characterized by elemental analysis, infrared spectroscopy, powder X‐ray diffraction, thermogravimetric analysis, and single‐crystal X‐ray diffraction analysis. Compound 1 exhibits a 2D (4,4) network, where each layer connects to four adjacent layers to construct a 3D supramolecular framework. Compound 2 has a 3D framework structure composed of 1D SUBs, which are formed by both carboxyl and tetrazole groups. The complexes represent two rare examples of CPs constructed from Hptz and organic carboxyl acid ligands. Complex 2 exhibits intense, red‐shifted emissions in the visible region at room temperature.
