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.
