Crystal structure of a mixed-ligand silver(I) complex of the non-steroidal anti-inflammatory drug diclofenac and pyrimidine

In the title mixed-ligand silver(I) coordination polymeric complex with the non-steroidal anti-inflammatory drug diclofenac (C(14)H(11)Cl(2)NO(2)) (diclH) and pyrimidine (pym), namely poly[{μ(2)-2-[2-(2,6-di­chloro­anilino)phen­yl]acetato-κ(2) O:O′}(μ(2)-pyrimidine-κ(2) N (1):N (3))silver(I)], [Ag(C(14)H(10)Cl(2)NO(2))(C(4)H(4)N(2))](n) or [Ag(μ-dicl)(μ-pym)](n), the very distorted tetra­hedral AgN(2)O(2) coordination 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⋯Cg hydrogen-bonding inter­actions between the sheets give an overall three-dimensional structure.
