Abstract The reaction of Gd(ClO 4 ) 3 ·6H 2 O with 5‐(1 H ‐tetrazol‐5‐yl)isophthalic acid affords a 3D framework gadolinium coordination polymer, [Gd(C 9 H 3 N 4 O 4 )(H 2 O) 3 ·2H 2 O] n ( 1 ). Its crystal structure belongs to a triclinic system, space group $P{\bar 1}$ , with a = 7.909(2) Å; b = 8.448(2) Å; c = 10.994(2) Å; α = 102.65(3)°; β = 124.32(2)°; γ = 96.28(3)°; V = 704.5(2) Å 3 ; Z = 2; R 1 = 0.0245 for 3225 reflections with I >2σ( I ), wR 2 = 0.0556. Fluorescent analyses show that compound 1 exhibits purple fluorescence in the solid state at room temperature.
