Designing coordination compounds with luminescent properties is a promising task due to applications of these compounds in organic light emitting diodes (OLED). Synthesis and luminescence study of silver(I) complexes is of current interest in modern coordination chemistry because bright fluorescence and phosphorescence of silver(I) complexes have been published. Emission of the complexes has been observed in visible and ultraviolet areas. In the present research we use pyrimidine-based ligands (Ln ) to synthesize Ag(I) complexes (Fig. 1). Coordination of π-deficient pyrimidine ligands to silver(I) ion may increase the photostability of these complexes. The various substituents in the pyrimidine ring significantly influence on the coordination modes of pyrimidine-based ligands, forming mononuclear and polynuclear silver(I) complexes.
