Abstract
Reaction of ZnII with 7-azaindole in methanol and in the presence of triethylamine gave a tetrameric zinc(II) complex characterized by X-ray crystallography to be [Zn4O(C7H5N2)6]. The measured intramolecular Zn ⋯ Zn separations and Zn–O distances are 3.147(2)–3.209(2) and 1.903(8)–1.975(8)Å respectively. At room temperature the cluster displays intense photoluminescence at 448 nm in the solid state and 425 nm in acetonitrile. The lifetime and quantum yield of the emission are 0.1 µs and 0.17 respectively.Keywords
