Tris(mercaptoimidazolyl)borate complexes of the coinage metals: syntheses and molecular structures of the first gold compounds and related copper and silver derivatives.
The first tris(mercaptoimidazolyl)borate complexes of gold, Au(Tm(tBu)) and (Tm(tBu))Au(PPh3), have been prepared and structurally characterized. Together with their copper and silver analogues M(Tm(tBu)) and (Tm(tBu))M(PPh3)(M = Cu, Ag), these compounds constitute the first two complete series of Tm(R) derivatives to be isolated for the coinage metals. In order to evaluate the steric and electronic effects of the bulky tert-butyl substituents in these species, comparative structural analyses with the known methyl-substituted analogue Ag(Tm(Me)) and various (Tm(Me))M(PR3) derivatives (M = Cu, Ag) are also presented.
