Abstract Two new Ag(I) coordination polymers [Ag2(mepyz)](2,6-ndc)]n (1) and [Ag4(4,4′-bipy)]4(2,6-ndc)2·8(H2O) (2) (where 2,6-ndcH2 = 2,6-napthalene dicarboxylic acid, mepyz = 2-methyl pyrazine and 4,4′-bipy = 4,4′-bipyridine) have been synthesized and characterized by single crystal X-ray diffraction analysis. Complex 1 displays a 2D rectangular grid architecture comprising short Ag···Ag interactions, while 2 is a 1D coordination polymer: both enlarge their dimensionality to 3D via weak interactions. Luminescence study performed on complexes as well on ligands shows metal perturbed intraligand CT transition. Graphical Abstract Two new luminescent coordination polymers of Ag(I) have been synthesized. The X-ray structural determination analysis revealed 2D and 1D coordination polymers that enlarge dimensionality to 3D via weak supramolecular interactions.
