摘要：

The synthesis and X-ray structural characterisation of a new Cu(II) complex, [Cu(L-1)Cl](ClO4)center dot CH3OH (1) [L-1 = N,N'-bis((pyridine-2-yl)phenylidene)-1,3-diaminopropan-2-ol], has been described in this work. The structural study reveals that the Cu(II) centre in 1 has a square pyramidal geometry with a trigonality index tau = 0.43, being coordinated by the organic ligand and a chloro group. The interaction of complex 1 and another complex previously reported by our group, [Cu(L-2)](ClO4)(2) (2) [L-2=N-(1-pyridin-2-yl-phenylidene)-N'-[2-({2-[(1-pyridin-2-ylphenylidene)amino]ethyl)amino)ethyl]ethane-1,2diamine], with calf thymus DNA (CT-DNA) has been investigated using absorption and emission spectral studies. The binding constant (K-b) and the linear Stern-Volmer quenching constant (K-sv) have been determined. (C) 2011 Elsevier Ltd. All rights reserved.
