Abstract In this paper, a novel rhenium (Ⅰ) complex (2) containing three carbonyl groups and another metal element,along with its precursor complex (1), were synthesized by the sequential reactions of bipyridyl polysulfide ligand (Ⅲ) with Ni(dbbpy)Cl₂ (dbbpy=4,4′-di-tert-butyl-2,2′-bipyridine) and Re(CO)₅Cl.¹H NMR, IR, MS and elemental analysis were employed to characte-rize the molecular structures of 1 and 2, and moreover, their crystallographic structures and optical properties were also investigated. Both 1 and 2 in CH₂Cl₂exhibit significant responses in the wavelength range of 250—305 nm with the molar extinction coefficients at 10⁴ level, but no fluorescence was observed. Finally we discussed the ground orbital energy of 1 and 2 via the density functional theory (DFT).

Key words： rhenium complex containing three carbonyl groups and another metal element bipyridyl polysulfide ligand optical property density functional theory (DFT)
