Özet

Utilizing a new 20-membered macrocyclic Schiff base ligand with two coordination sites formed from the [2+2] condensation of 1 3-diaminopropane and benzene-1 3-chcarboxaldehyde in the presence of CuX (X = Cl- Br- I-) salts air-stable dicopper(I) complexes were synthesized in acetonitrile intramolecularly linked via two halide groups and characterized by different physico chemical techniques The single crystal X-ray diffraction technique indicates these complexes consist of two N2X2 donor sets that have distorted tetrahedral coordination environments around the copper(I) ions In these halogen-bridged binuclear Cu2LX2 systems the Cu Cu separation can be controlled as this distance is reduced on increasing the halide size and hence the X X repulsion with the rigidity of the macrocycle playing a significant role (C) 2010 Elsevier Ltd All rights reserved
