Syntheses, Crystal Structures And Spectroscopic Properties Of Mono-oxime Ligands And Its Cu (?) And Zn (?) Complexes

Coordination chemistry as a branch of separated from inorganic chemistry, chemical workers widely attention in recent years.Metal complex valence and space structure, make it has some special properties, thus in the chemical production and won the high and new technology development important application, become one of the most studied types of compounds.At present, the research field of coordination chemistry has penetrated into many other subjects.This not only makes coordination chemistry of chemical branch channel and intersection, and go deep into the areas such as material, physical, information and energy caused by the relevant workers pay close attention to.Oxime compounds in coordination chemistry is a kind of very important ligands containing nitrogen, oxygen, and this kind of compounds by containing active carbonyl group of aldehydes or ketones with hydroxylamine occurred such as the formation of condensation reaction.They contain ?C=N-OR? groups have very good coordination function, coordination of atomic oxygen is great electronegativity and the metal atoms have better coordination effect is easy to form organic metal complexes.Oxime, drug intermediates in the synthesis of chiral amine and biological activity of all kinds of heterocyclic compounds and so on also has great potential.So build with oxime compounds complex carbon-carbon, carbon-heteroatomic keys have been chemical workers are one of the important areas of concern.In recent decades, scholars in the study of transition metal complexes, has made considerable progress, and found many effective system.As a result of oxime compounds in areas such as sterilization, insecticidal, anticancer and antiviral were widely used, especially in analytical chemistry, medicine, metal corrosion and functional materials is more outstanding.In this article, therefore, the preparation of a series of new type oxime ligands HL¹, HL², HL³, HL⁴, HL⁵, and have been characterized to determine the structure, through the ligand with metal ions obtained the corresponding complexes:[Zn?L¹?₂] ?1?, [Cu?L¹?₂] ?2?, [Cu?L²?₂] ?3?, [Cu?L³?₂] ?4?.Using elemental analysis, infrared spectrum analysis, ultraviolet spectrum analysis for the characterization, the fluorescence spectrum of its further research, the optical properties of got by the method of X-ray single crystal diffraction crystallography data and spatial structure.Crystallography data is as follows:[Zn?L¹?₂]:Empirical formula,C₃₄H₃₆Cl₂N₄O₆Zn,Formula weight,732.96,Crystal system, Triclinic,Space group, P1,Unit call dimensions:?= 10.6293?13????, b= 12.2147?14?
