Abstract

In the title mixed-ligand silver(I) coordination polymeric complex with the non-steroidal anti-inflammatory drug diclofenac (C₁₄H₁₁Cl₂NO₂) (diclH) and pyrimidine (pym), namely poly[{μ₂-2-[2-(2,6-di-chloro-anilino)phen-yl]acetato-κ²O:O'}(μ₂-pyrimidine-κ²N¹:N³)silver(I)], [Ag(C₁₄H₁₀Cl₂NO₂)(C₄H₄N₂)] _n or [Ag(μ-dicl)(μ-pym)] _n , the very distorted tetra-hedral AgN₂O₂ coordination centres comprise two N-atom donors from bridging pym ligands [Ag-N = 2.381 (3) and 2.412 (3) Å] and two carboxyl-ate O-atom donors from dicl ligands [Ag-O = 2.279 (2) and 2.280 (2) Å], which bridge Ag atoms, giving a centrosymmetric dinuclear units with a short Ag⋯Ag separation [2.8931 (5) Å]. Within the units are short intra-ligand C-Cl⋯π(pym) inter-actions [3.6409 (15) Å]. The units are linked through the bridging N atoms of the pym ligand into a two-dimensional sheet-polymer structure lying parallel to (100) and stabilized by inter-ring π-π inter-actions between the pym ligands [Cg⋯Cg = 3.4199 (17) Å]. Additional inter-unit C-H⋯O and C-H⋯Cg hydrogen-bonding inter-actions between the sheets give an overall three-dimensional structure.
