چکیده
This study reports chromotropism of two newly synthesized copper(II) complexes formula [CuLCl2] and [CuLBr2]•MeOH where L = N-(2-pyridylmethyl)-1-hydroxypropylamine. The structure the was investigated by infrared spectroscopy, electronic absorption elemental analysis, molar conductance measurements, thermal analysis. Single Crystal X-ray determination reveals both to adopt a distorted square-pyramidal geometry. Their chromotropic properties were using spectroscopy. are solvatochromic in solvents with different polarities. aqueous solutions exhibit variety colors pH range 1.8 11.4 showing that compounds halochromic. also thermochromic show reversible color changes temperatures dimethyl sulfoxide solutions. solution observed originates from structural conditions.

The tridentate ONO-donor Schiff base ligand H2L, derived from the condensation of 1-anisyl-1,3-butanedione and 2-aminophenol, was generated in situ and reacted with Cu(NO3)2•3H2O to yield two doubly phenoxo bridged di-copper(II) complexes depending on the nitrogenous base used. [Cu2L2] (1) is obtained in 85% and 75% yield in the presence of pyridine or 4-picoline, respectively, and [(py-tBu)2Cu...
