2D and 1D Coordination Polymers of Ag(I) Ions with 2,6-Naphthalenedicarboxylate and N–Donor Coligands

Two new Ag(I) coordination polymers [Ag2(mepyz)](2,6-ndc)]n (1) and [Ag4(4,40-bipy)]4(2,6-ndc)2.8(H2O) (2) (where 2,6-ndcH2 = 2,6-napthalene dicarboxylic acid, mepyz = 2-methyl pyrazine and 4,40-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.
