Abstract
Three new centrosymmetric dinuclear copper(II) complexes, [Cu2Cl2(L1)2] (1), [Cu2(μ 1,3-NCS)2(L2)2] (2), and [Cu2(μ 1,1-N3)2(L3)2] (3), where L1, L2, and L3 are the deprotonated forms of the Schiff bases 1-[(2-propylaminoethylimino)methyl]naphthalen-2-ol (HL1), 1-[(3-methylaminopropylimino)methyl]naphthalen-2-ol (HL2), and 2-[(2-isopropylaminoethylimino)methyl]phenol (HL3), respectively, have been prepared and characterized by elemental analysis, IR spectra, and single-crystal X-ray crystallography. Each Cu is coordinated by the three donors of the Schiff bases and by two bridging groups, forming a square-pyramidal geometry.
