Zn的3,5-二溴水杨醛水杨酰腙配合物的合成、表征及晶体结构

Synthesis,Characterization and Crystal Structure of the Complexes of Zinc with 3,5-Dibromosalicylaldehyde Salicylhydrazone

The title complex [Zn(C14H8N2O3Br2)(C5H5N)3] was synthesized in DMF and pyridine. It has been characterized by IR, element analysis and X-ray diffraction analysis. The crystal structure of the title complex belongs to monoclinic space group P21 / c with cell parameters: a=0.999 78(6) nm, b=1.951 11(13) nm, c=1.496 02(10) nm, β=97.126 0(10)°, and V=2.895 7(3) nm3, Dc=1.639 g·cm-3, Z=4, F(000)=1 424, μ=3.647 mm-1, the final R=0.061 0 and wR=0.140 2 for 3 528 observed reflections with I>2σ(I). The X-ray crystal structure analysis revealed that the center zinc(Ⅱ) is bonded to two oxygen atoms and one nitrogen atom from a tridentate ligand and three nitrogen atoms from three solvent pyridine molecules to form a six-coordinate octahedron. CCDC: 261047.
