Triphenylphosphine-supported synthesis of two-dimensional silver(I) complex with (1,3,4-thiadiazole-2,5-diyldithio)diacetic acid
Abstract
<p>The reaction of dicarboxylate ligand, (1,3,4-thiadiazole-2,5-diyldithio)diacetic acid (H<sub>2</sub>tdza) with silver(I) acetate and triphenylphosphine (PPh<sub>3</sub>) facilitate the formation of complex [Ag<sub>2</sub>(tdza)(PPh<sub>3</sub>)<sub>2</sub>]<i><sub>n</sub></i> <b>(1)</b>. The complex was characterized by elemental analysis, FT-IR spectroscopy, <sup>1</sup>H-NMR, <sup>13</sup>C-NMR and <sup>31</sup>P-NMR spectroscopy, and single crystal X-ray diffraction. Structural analysis revealed that complex <b>1</b> has a 2D topologically promising architecture as a result from the formation of 26-membered cyclic ring. The tdza2<sup>−</sup> ligand in <b>1</b> displays unprecedented µ<sub>4</sub>-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 <b>1</b>.</pSimilar works
