The crystal structure of a suitable single crystal prepared by slow evaporation was determined by single crystal X-ray diffraction. The compound crystallized in the triclinic system with space group <em>P</em>-1 and Z = 2. X-ray results showed that the neutral thiosemicarbazone ligand 4nb-tsc was coordinated to silver(I) ion in two different bonding modes, <em>μ</em>-S, and η<sup>1</sup>-S. The shortest distance between the sulfur-bridged Ag cations was 3.576(5) Å. One P atom and three S atoms from three 4nb-tsc ligands coordinated to the silver(I) ion in a distorted tetrahedral geometry. In the crystal packing of the title compound, several hydrogen bonds were connecting the molecules of the complex. nanoparticles Dinuclear silver(I) Thiosemicarbazone Sulfur-bridged Tetrahedral geometry https://jsciences.ut.ac.ir/article_71748_c879fab41262cf7a2a0d3ee3c09e6f37.pdf
