Abstract
We report here the synthesis of bis(DEDT –S,S)-μ-(naphthyl-1,8) digold(II) (1) (DEDT = diethyldithiocarbamate) with a formal Au-Au bond. Complex 1 is formed from the reaction of Au(DEDT)Cl2 with 1,8-dilithioaphthalene, a unique synthesis as gold(II) complexes are traditionally synthesized by oxidative addition of digold(I) complexes. Complex 1 was characterized by NMR, UV-Vis spectroscopy, X-ray and elemental analysis. Density Functional Theory calculations suggests the UV-Vis absorption of complex 1 at 379 nm is a transition from the σ(Au-Au) orbital into the σ*(Au-Au) orbital with some contribution from DEDT-to-metal charge transfer (LMCT). Complex 1 shows no emission at 298 K or 77 K, presumably because low-lying 3LMCT states foster rapid non-radiative decay.
