Synthesis and Study of Copper(II),Nickel(II),and Cobalt(II)Complex Compounds with Dihydrobenzoxazine Derivatives

摘要

Complex compounds ML_2 of copper(II),nickel(II),and cobalt(II)with 2-(2-hydroxy-5-nitro-phenyl)-4,4-diphenyl-1,4-dihydro-2H-3,1-benzoxazine and 2-(2-hydroxyphenyl)-4,4-diphenyl-1,4-dihydro-2H-3,1-benzoxazine (HL)were prepared by electrochemical and chemical syntheses.The complex formation involves the azomethine form of the ligand and gives a six-membered chelate cycle comprising deprotonated phenol and azomethine groups.The coordination entity has a planar structure with trans arrangement of the nitrogen and oxygen atoms.
