Abstract
ABSTRACT: A new tripodal ligand, N,N-Bis(3,5-dimethylpyrazol-1-ylmethyl)-1-hydroxy-4-aminobutane (bpmhb), has been synthetized. Reaction of (bpmhb) with Copper (II) chloridedihydrate [CuCl2, 2H2O] in methanol produced the new complex Cu(bpmhb)Cl2. Thecomplex crystallizes in the monoclinic system, space group P21, the cell dimensions are a =7.990 Å, b = 14.620 Å, c = 8.590 Å, α = 90°, β = 95.80°, γ = 90°, V= 998.3 Å3 and Z =2.The single-crystal X-ray structure of the title compound, N,N-Bis(3,5-dimethylpyrazol-1-ylmethyl)-1-hydroxy-4-aminobutane Copper(II) dichloride shows that the surroundinggeometry of the copper (II) ion can be described as being intermediate between a distortedsquare pyramid and a trigonal bipyramid. The OH group function form an intramolecularhydrogen bonding with the chloride atom Cl1.With molecular oxygen as oxidant, this complex catalyzed the conversion of catechol toquinone with a good catalytic activity.
