Abstract

The reaction of (isocyanide)gold(I) chlorides [(RNC)AuCl, R = tBu, cHex] with phenylene-1,2-dithiol and sodium methoxide (molar ratio 2:1:2) in methanol / dichloromethane leads to the formation of deep green mixed-valent salts [(RNC)2Au]+[Au(S2C6H 4)2]- in ca. 35% yield. As determined by single crystal X-ray diffraction methods, the two compounds have entirely different supramolecular structures. For R = tBu stacked planar anions and rod-like cations form alternating layers, while for R = cHex alternating cations and anions are arranged in chains with long S- -Au contacts [3.422 Å].
