Abstract
The tetranuclear [{Au(PPh3)}4(μ-bbzim)][ClO4]2 and dinuclear [{Au(PPh3)}2(μ-bbzim)] complexes with 2,2′-bibenzimidazolate (bbzim) as bridging ligand have been characterized by X-ray crystallography. The intramolecular Au-Au separations in [{Au(PPh3)}4(μ-bbzim)][ClO4]2 are 3.157(1)-3.222(1) Å. Upon excitation at 330 nm, both complexes display intense intraligand fluorescence and phosphorescence in fluid solution at room temperature.
