Two novel Ag（I） coordination polymers （CPs）, namely, [Ag2（L1）C1] （1） and [Ag9（L2）8]oNO3 （2）, （LI= 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 AgC1 chains with the point （Schlafli） symbol {4~82} {40830102} {42＊6＊82＊10} {42＊6}, in which Ag…Ag distances fall in the region of 3.129（2） to 3.731（1） A. In contrast, different topological structure was presented substituting the L1 by L2. Complex 2 exhibits the 2D layer with the point （Schlafli） symbol {4＊62}2{42＊62＊82} {5＊62}2{52＊6}2{54＊82}, in which Ag…Ag distances fall in the region of 2.867（1） to 3.116（1） A. 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.
