摘　　要：A novel dimeric complex [Ru3 (μ3-O)(μ-CH3COO)(CO)]2(μ-dppf)(μ-odppf)(dppf = 1, 1'-bis(diphenylphosphio)ferrocene, odppf = 1, 1'-bis(oxodiphenylphosphoranyl)ferrocene) (1) of oxo-centered triruthenium-aectate cluster units was synthesized and characterized by X-ray crystallography. Compound 1 exhibits a cyclic structure formed by linkages of two triruthenium cluster units Ru3 (μ3-O)(μ-CH3COO)6(CO) through dppf and odppf ligands, respectively. The diameter of the molecular loop is ca. 1.0 nm.A novel dimeric complex [Ru3 (μ3-O)(μ-CH3COO)(CO)]2(μ-dppf)(μ-odppf)(dppf = 1, 1'-bis(diphenylphosphio)ferrocene, odppf = 1, 1'-bis(oxodiphenylphosphoranyl)ferrocene) (1) of oxo-centered triruthenium-aectate cluster units was synthesized and characterized by X-ray crystallography.
