Synthesis, Crystal Structure, and Selected Properties of [Au(S CNH ) ]SCN: A Precursor for Gold Macro-Needles Consisting of Gold Nanoparticles Glued by Graphitic Carbon Nitride.

A new preparation route is developed for the synthesis of needle-like crystals of [Au(S CNH ) ]SCN, which avoids disproportionation of the Au salt used as a starting material. In the crystal structure, the two crystallographically independent Au centers are in a square-planar environment of two S CNH ligands. The Hirshfeld surface analysis reveals the presence of noncovalent intermolecular S⋅⋅⋅S interactions, which are essential for the spatial arrangement of the molecules.
