Synthesis, Crystal Structure and Catalytic Activity of Tri-Nuclear Zn(II) Complex Based on 6-Phenylpyridine-2-carboxylic Acid and Bis(4-pyridyl)amine Ligands

A new trinuclear Zn (II) complex, [Zn3(L1)4(L2)2(CH3COO)2] (1) (HL1 = 6-phenylpyridine-2-carboxylic acid, L2 bis(4-pyridyl)amine) has been synthesized by NaOH, bis(4-pyridyl)amine and Zn(CH3COO)2•2H2O. The complex 1 also structural characterized elemental analysis single crystal X-ray diffraction. results reveals that is made up of three Zn(II) ions, four L1 ligands, two ligands CH3COO- anions. In 1, both Zn1 ion Zn1a are five-coordinated with O atoms from different N one ligand, respectively, forms a distorted trigonal biyramid geometry. And Zn2 four-coordinated CH3COO? anions forming tetrahedral Complex displays 3D network structure the intermolecular N?H···O hydrogen bonds. catalytic performance for oxidation benzyl alcohol O2 was studied under mild reaction conditions using as catalyst. demonstrated catalysts were very active, yield benzaldehyde 50.8% at 90 °C THF solvent 0.5 MPa within 3 h.
