Two novel silver(I) complexes with diclofenac, ({2-(2,6-dicholoroanilino)phenylacetic acid} = dicl) namely [Ag(dicl)]n (1) and [Ag(dicl)(bipy)]n (2) (bipy: 4,4'-bipyridine), have been synthesized and characterized by elemental analysis, IR spectroscopy, thermal analysis and single-crystal X-ray diffraction. X-ray crystallographic data of 1 revealed that dicl anion adopts a μ3-η1,η2 coordinated mode link three Ag atoms generate 1D infinite chain structure. In 2, dicl ligand plays crucial role to form double-ladder chain structure, clamping two neighboring [Ag(μ-bipy)]∞ chains by using carboxylate oxygen atoms (O1, O2). The most interesting structural feature of 2 is the presence of strong π···π interactions between aromatic phenyl rings of dicl placed in the adjacent 1D chains, leads to forming 2D slab structure. The coordination modes of dicl in the title complexes are supported by using IR spectroscopy. Thermal stabilities of 1 and 2 have been determined by TG/DTA/DTG techniques. The luminescent properties of complex 1 and 2 have been investigated in the solid state at room temperature. Furthermore, the title complexes have been tested for their in vitro antibacterial activities and are determined to be highly effective for antibacterial activity against Gram(+) and Gram(−) pathogenic bacteria cells. 1 and 2 showed activity on Fungi, as well. Two novel silver(I) complexes with the anti-inflammatory diclofenac (dicl), namely [Ag(dicl)]n (1) and [Ag(dicl)(bipy)]n (2) (bipy: 4,4'-bipyridine), have been synthesized and characterized by elemental analysis, IR spectroscopy, thermal analysis and single-crystal X-ray diffraction. Their solid state photoluminescence properties have been studied at room temperature. Furthermore, both complexes have been tested for their in vitro antibacterial activity.
