Synthesis and X-ray structures of dinuclear and trinuclear gold(I) and dinuclear gold(II) amidinate complexes
The structures of the trinuclear gold(l), [Au-3(2,6-Me-2-form)(2-)(THT)Cl], the dinuclear [Au-2(2,6-Me-2-form)(2)], and the oxidative addition product [Au-2(2,6-Me-2-form)(2)Cl-2] formamidinate complexes are reported. The trinuclear complex is stable with gold-gold distances 3.01 and 3.55 Angstrom. The gold-gold distance in the dinuclear complex decreases upon oxidative-addition with halogens from 2.7 to 2.5 Angstrom, similar to observations made with the dithiolates and ylides.
