A water stable tetrazolate‐containing metal‐organic framework, [Cd 2 (L)(OH)(H 2 O) 2 ] n ( 1 ) [H 3 L = 5‐(4‐(tetrazol‐5‐yl)phenyl)isophthalic acid], was synthesized under solvothermal conditions and structurally characterized. Compound 1 displays a three dimensional porous network with one dimensional tubular channels based on trinuclear cluster [Cd 3 (μ 3 ‐OH)N 4 C] units. Notably, 1 exhibits highly sensitive response to Cu 2+ and Cr 2 O 7 2– through luminescence quenching effects with the detection limit of 0.666 ppm for Cu 2+ and 0.846 ppm for Cr 2 O 7 2– , respectively. The possible mechanism of the luminescence quenching was discussed in detail.
