| Abstract: One novel binuclear cadmium(Ⅱ) Complex [Cd2(phen)2(C15H11O3)4]·(H2O) with o-methylbenzoyl-benzoic acid and 1,10-phenanthroline(phen) has been synthesized by means of hydrothermal way and characterized. It was characterized as crystallizing in the Triclinic space group P1, with a=1.1155(2)nm, b=1.2069(2)nm, c=1.4355(3) nm, α=99.79(3)°, β=111.27(3)°, γ=98.17(3)°, V=1.730 5(6) nm3, Dc=1.514 g·cm-3, Z=1, F(000)=804. Final GooF=1.060, R1=0.024 7, wR2=0.063 2. The crystal structure shows that the cadmium ion is coordinated with four oxygen atoms from three o-methylbenzoyl-benzoic acid radical, two nitrogen atoms from one 1,10-phenanthroline molecule, forming a distorted octahedral coordination geometry. There exist two coordination types with the o-methylbenzoyl-benzoic acid, which coordination with the center cadmium ion with the bridging and chelating bidentatein types. Two o-methylbenzoyl-benzoic acid molecules and two cadmium(Ⅱ) ions form a octatomic ring structure, and the Cd(Ⅱ)…Cd(Ⅱ) distance is 0.419 8 nm. The result of TG analysis shows that the title complex was stable under 220.0 ℃. CCDC: 741934. |
