The two‐dimensional (2D) cluster‐based silver(I) complex {[Ag 2 (μ 3 ‐L 1 ) 2 (μ 2 ‐HL 1 )] · H 2 O · 3NO 3 } n ( 1 ) was isolated under hydrothermal conditions using the multi‐dentate triazole derivative ligand 4‐(4‐aminobenzene)‐1, 2, 4‐triazole (L 1 ) and the corresponding silver(I) salts. The results indicate that 1 is constructed by tetranuclear Ag I clusters as secondary building blocks. Each tetranuclear Ag I cluster links four neighboring Ag I clusters by eight bridging μ 3 ‐L 1 ligands forming a two‐dimensional (2D) microporous cluster‐based framework. Compound 1 also represents a scarcely reported example of coordination frameworks with 4‐(4‐aminobenzene)‐1, 2, 4‐triazole. The solid‐state fluorescence spectrum of 1 exhibits strong red‐shifted enhanced photoluminescence emission in comparison with that of free L 1 . The versatile bidentate and tridentate coordination modes of L 1 in 1 together with flexible dihedral angles between aromatic benzene and triazole rings also reveal great potential in the construction of functional frameworks with L 1 .
