溶剂热合成5－氯－8－羟基喹啉－锑（III）配合物
Solvothermal synthesis of antimony(III) complex based on 5-chloro-8-hydroxyquinoline
摘要
Abstract
The new dinuclear antimony complex 1 that features aryloxide ligand,namely [(SbL2)2(μ2-O)] (L=5-chloro-8-hydroxyquinoline anion ) was synthesized hydrothermally from metal antimony and 5-chloro-8-hydrox-yquinoline (HL) in methanol/water system. Water played a very important role in the synthesis of complex 1. Its structure was characterized by IR ,elemental analysis and single crystal X-ray diffraction analysis. Complex 1 be-longs to monoclinic system and space group P21/c with unit cell parameters a=7.402 2(4) Å,b=7.672 1(5) Å,c=28.898(2) Å,β=94.217(7)°,V=1 636.68(19) Å3,Z=2. Antimony(III) ion is five coordinate and square pyrami-dal coordination geometry,and two antimony (III) ions are bridged by the oxygen atom to form a dinuclear molecule. A quasi-one-dimensional chain structure along the a direction was formed through intermolecular π-π,Sb···Sb and Sb···O interactions. These quasi-one-dimensional chains were joined to a quasi-three-dimen-sional structure by the intermolecular C-H···Cl hydrogen bonds. The thermal stability of compound 1 is stable at 409℃. The solid Uv-Vis-Nir diffuse reflectance spectra show that the optical energy gap of the solid is about 2.7 eV,which indicates that the complex 1 has the potential semiconductor property.关键词
