W. Schneider et al., (ISOCYANIDE)GOLD(I) THIOSALICYLATES - SUPRAMOLECULAR ASSEMBLY BASED ON BOTH AURIOPHILIC AND HYDROGEN-BONDING, Organometallics, 15(26), 1996, pp. 5445-5446
Reaction of(RNC)AuCl[R=tert-butyl (1a), mesityl (1b)] with sodium thio
salicylate in the two-phase system water/dichloromethane gives high yi
elds of the corresponding (isocyanide)gold(I) thiosalicylates (2a,b).
The solid-state structures of 2a,b have been determined by X-ray diffr
action studies. The supramolecular structure of both compounds is gove
rned by Au-Au interactions [2a, Au-Au 3.157(2) Angstrom; 2b, Au-Au 3.3
186(5) Angstrom] and hydrogen bonding through the carboxylic acid grou
ps.
