GRAPHICAL ABSTRACT

ABSTRACT

The reaction of dicarboxylate ligand, (1,3,4-thiadiazole-2,5-diyldithio)diacetic acid (H2tdza) with silver(I) acetate and triphenylphosphine (PPh3) facilitate the formation of complex [Ag2(tdza)(PPh3)2]n (1). The complex was characterized by elemental analysis, FT-IR spectroscopy, 1H-NMR, 13C-NMR and 31P-NMR spectroscopy, and single crystal X-ray diffraction. Structural analysis revealed that complex 1 has a 2D topologically promising architecture as a result from the formation of 26-membered cyclic ring. The tdza2 ligand in 1 displays unprecedented µ4-bridging mode which is also the first example for this ligand. The interdigitating arrangement and π-π stacking between 2D arrays stabilized the formation of complex 1.
