Structural Investigation of Bis(isonitrile)gold(I) Complexes

The reaction of (MeNC)-, (PhNC)- and (MesNC)AuCl in tetrahydrofuran with an equimolar amount of the corresponding isonitrile ligand and one equivalent of Ag+X- (X- = BF-4 or CF3SO-3) leads to the formation of the bis(isonitrile)gold(I) complexes (MeNC)2Au+ CF3SO-3 (1), (PhNC)2Au+ BF-4 (2) and (MesNC)2Au+ BF-4 (3). The crystal structures of 1, 2 and 3 have been determined. In compound 1 there are rod-like cations with a parallel packing into meandering puckered layers, in which the gold atoms have alternating Au-Au contacts of 3.611 and 3.624 A. In complex 2 the cations form long double-paddles, with the two paddles at an angle of 77.5°. The individual cations are well separated and have no sub-van-der-Waals Au-Au contacts. The crystal structure of 3 is similar, but with a smaller dihedral angle between the planes of the two mesityl rings (56.0°).
