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

Abstract

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\ud by single crystal X-ray diffraction analysis. Complex 1 displays a 2D rectangular grid architecture comprising\ud 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\ud as well on ligands shows metal perturbed intraligand CT\ud transition

“…In addition a water molecule is bound at each silver atom at longer distance (Ag(1)–O(8w)=2.895(3) Å, Ag(2)–O(7w)=2.780(3) Å), so that the metals adopt a non‐trigonal tri‐coordinated geometry. The Ag–N bond lengths (Table S3) are comparable to those noticed in related complexes, but slightly shorter by ca. 0.03 Å than those measured in CP 1 .…”

“…2). The Ag–N bond distances fall in the range 2.152(6)‐2.193(6) Å, while Ag–O interactions are significantly longer, in between 2.630(6)‐2.889(6) Å, as detected in similar complexes . As a matter of fact Ag(I) ions 1,3,4,6,8 are tri‐coordinated while 2,5,7 are tetra‐coordinated (Table S2).…”

New Silver(I) Coordination Polymers with Hetero Donor Ligands: Synthesis, Structure, Luminescence Study and Photo-Catalytic Behavior

“…As Ag + ion is a d 10 system, oxidation or reduction of this metal center is extremely difficult. In this context, comparing the emission profile of the free ligands with their complexes 2 and 3 we can conclude that the emission behavior of 2 and 3 is a collective effect of the metal perturbed intra ligand π*–π and π*–n CT transition ,…”

Influence of Flexible Bis(benzimidazole) Derivatives on the Self‐assembly of Three Mixed Ligands Silver(I) Coordination Polymers

“…[9][10][11][12][13][14] As an important member of multidentate O-donor ligands, 1,4-naphthalenedicarboxylic acid (1,4-H 2 ndc) seems to be an excellent building block with charge, versatile coordination modes as well as remarkable stability for constructing multidimensional networks. [15][16][17] The combination with neutral Ndonor ligands and anionic O-donor ligands can generate more robust network structures, which cannot be obtained only via one type of ligands.
