摘要
A novel dinuclear zinc（II） complex [Zn2L（μ-OAc）]（PF6）2（CH3OH） has been synthesized from a new symmetrical compartmental ligand HL in which the pendant arms, bearing pyridyl groups, are bridged by 1,3-diaminopropan-2-ol. X-ray crystal structure shows that the two zinc atoms reside within the adjacent ligand compartments and are bridged by the endogenous alkoxo-O from ligand and one exogenous carboxylate from acetate with a syn-syn mode. The coordination geometry of two zinc atoms is a distorted trigonal bipyramid with the pyridyl-N atoms and bridging alkoxo-O atom providing the equatorial donor set. Such coordination geometry observed in this complex is similar to that found in the dinuclear unit ofphospholipase C.
