The crystalline silver(I) p,scomplex [Ag(2-aphtr)ClO₄] (I) (2-aphtr = 2-allyl-5-phenyl-2H-tetrazole, C₁₀H₁₀N₄) was obtained starting from Ag₂CO₃, HClO₄ and the organic ligand 2aphtr in ethanol, and studied by single crystal X-ray diffraction. The crystal structure is triclinic, space group P-1, a = 6.3078(12), b = 7.0690(15), c = 14.566(3) Å, α = 80.780(12), β = 88.148(12), γ = 79.759(13)°, V = 630.9(2) ų at 200 K, Z = 2. The Ag(I) atom possesses a trigonal pyramidal coordination environment involving the C=C bond of an allyl group, two N atoms from two adjacent tetrazole molecules and one perchlorate O atom, which occupies the apical position of the coordination polyhedron. Bridging Ag(I) atoms connect the 2-aphtr molecules into infinite {Ag(2-aphtr)ClO₄}_n chains. π×××π-Stacking of aromatic rings of neighboring chains is observed.
