Abstract
Attempts to isolate the compound (tu2Au)SCN 1 (tu=thiourea), first reported in 1949, at first led to [(tu)2Au]2SO4·CH3OH 2 after crystallization from methanol-petroleum ether. Crystallization from isopropanol led to the required compound 1. The crystal structure analysis of 1 confirmed its ionic nature, (tu2Au)+ SCN−. The tu ligands are mutually trans (torsion angle C–S···S–C 175.4(2)°), and the entire cation is approximately planar (r.m.s. deviation 0.08 Å). Eight classical hydrogen bonds connect the residues to form layers parallel to the bc plane at x≈⅛, ⅜, ⅝ and ⅞; the layers are connected by aurophilic contacts, which link the cations to form chains parallel to the a axis. In the structure of compound 2 the S=C groups are synclinal to each other; two NH2 groups are connected via a bifurcated hydrogen bonding system to a sulfate oxygen, forming a ring of graph set
