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-dichloroanilino)phenyl]acetato-κ2O:O′}(μ2-pyrimidine-κ2N1:N3)silver(I)], [Ag(C14H10Cl2NO2)(C4H4N2)]nor [Ag(μ-dicl)(μ-pym)]n, the very distorted tetrahedral AgN2O2coordination centres comprise two N-atom donors from bridging pym ligands [Ag—N = 2.381 (3) and 2.412 (3) Å] and two carboxylate 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 intraligand C—Cl...π(pym) interactions [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 interactions between the pym ligands [Cg...Cg= 3.4199 (17) Å]. Additional inter-unit C—H...O and C—H...Cghydrogen-bonding interactions between the sheets give an overall three-dimensional structure.
