| 摘 要： | 1 INTRODUCTION The interest in the complexes of transition metals with ligands ketoxime1, 2] as potential models for metal binding sites in ferroverdin3, 4] has prompted the investigation on the structures and the overall coordination geometry of the metal centers in these complexes. Oxime derivatives are interesting ligands since the ketoximes are found to chelate transition metals through the N (oxime) and O (ketone) atoms5, 6]. However, monodentate coordination via only one O or …

| Abstract: | The title complex, bis(indene-1,2,3-trione 2-oximato)bis(aqua)Mn(Ⅱ), crystallizes in the monoclinic system, space group P21/c with a = 5.201(1), b = 16.547(3), c = 9.914(2) A, β =100.30(3)°, V = 839.4(3) A3, Dc = 1.738 g/cm3, F(000) = 446, C18H12N2O8Mn, Mr = 439.24,μ(MoKα) = 0.842 mm-1, Z = 2, the final R = 0.0228 and wR = 0.0782 for 1762 observed reflections (Ⅰ≥ 2σ(Ⅰ)). The geometry around Mn(Ⅱ) is adistorted octahedral configuration with the basal plane consisting of two oximo-oxygen and two carbonyl-oxygen atoms from ligand indene-l,2,3-trione 2-oximato, while the axial coordination sites are occupied by two wateroxygen atoms. A plane network is formed by the intermolecular hydrogen bonds. The title complex is the first example of metal complex containing ligand indene- 1,2,3-trione 2-oxime. |
