Synthesis and X-ray Structures of Dinuclear and Trinuclear Gold(I) and Dinuclear Gold(II) Amidinate Complexes<sup>†</sup> Hanan E. Abdou Ahmed A. Mohamed John P. Fackler 10.1021/ic048855q.s003 https://acs.figshare.com/articles/dataset/Synthesis_and_X_ray_Structures_of_Dinuclear_and_Trinuclear_Gold_I_and_Dinuclear_Gold_II_Amidinate_Complexes_sup_sup_/3303583 The structures of the trinuclear gold(I), [Au<sub>3</sub>(2,6-Me<sub>2</sub>-form)<sub>2</sub>-(THT)Cl], the dinuclear [Au<sub>2</sub>(2,6-Me<sub>2</sub>-form)<sub>2</sub>], and the oxidative-addition product [Au<sub>2</sub>(2,6-Me<sub>2</sub>-form)<sub>2</sub>Cl<sub>2</sub>] formamidinate complexes are reported. The trinuclear complex is stable with gold−gold distances 3.01 and 3.55 Å. The gold−gold distance in the dinuclear complex decreases upon oxidative-addition with halogens from 2.7 to 2.5 Å, similar to observations made with the dithiolates and ylides. 2005-01-24 00:00:00 trinuclear dinuclear 2 Cl 2 3.55 Å.
