Two novel Ag(I) coordination polymers (CPs), namely, [Ag 2 (L1)Cl] ( 1 ) and [Ag 9 (L2) 8 ]·NO 3 ( 2 ), (L1=4‐(4‐carboxyl)‐2,2:4′,4‐terpyridine), L2=4‐(4‐carboxyl)‐2,2′:6′,2′′‐terpyridine), have been synthesized through solvothermal reaction of silver(I) nitrate and highly‐connected terpyridinate‐carboxyl ligands and structurally characterized. Complex 1 exhibits the 3D network based on 1D AgCl chains with the point (Schl?fli) symbol {4·8 2 }{4·8 3 ·10 2 }{4 2 ·6·8 2 ·10}{4 2 ·6}, in which Ag···Ag distances fall in the region of 3.129(2) to 3.731(1) Å. In contrast, different topological structure was presented substituting the L1 by L2. Complex 2 exhibits the 2D layer with the point (Schläfli) symbol {4·6 2 } 2 {4 2 ·6 2 ·8 2 }{5·6 2 } 2 {5 2 ·6} 2 {5 4 ·8 2 }, in which Ag···Ag distances fall in the region of 2.867(1) to 3.116(1) Å. The different coordination modes of the terpyridiante‐carboxyl ligands must be responsible for the variable Ag(I) coordination architectures. Additionally, results about TGA, UV‐vis, photoluminescence spectra and electrochemistry were also discussed.
