Abstract: 
The dinuclear copper(II) complexes {[Cu-2(1,3-tpbd)-(H2O) (OAc)(2)] (ClO4)2}(0.23) {[Cu-2(1,3-tpbd) (H2O)(2)(OAc)]-(ClO4)(3)}(0.7)(.)0.77H(2)O (1), [Cu-2(1,3-tpbd)(H2O)(2)(OAc)(2)]- (ClO4)(2)(.)2H(2)O (2), and the tetranuclear copper(II) complex [Cu-4(1,3-tpbd)(2)(H2O)(2)(SO4)(4)](.)8H(2)O (3) {1,3-tpbd = 1,3-bis [bis(2-pyridylmethyl)amino]benzene} were synthesised and structurally characterised by X-ray diffraction. Variable-temperature (2.0-290 K) magnetic susceptibility measurements on these complexes as well as on the dinuclear copper(II) Complex [Cu-2(1,3-tpbd)(H2O)(2)(ClO4)(3)]ClO4 (4) (whose structure was published earlier) were performed. In contrast to 2 and 3, significant ferromagnetic coupling with J = +9.3 cm(-1) was observed for 4 (the Hamiltonian being defined as (H) over cap = -J (S) over cap (.)(1)(S) over cap (2)). Density functional theory (DFT) calculations were used successfully for the interpretation of the ferromagnetic coupling observed in 4. (C) Wiley-VCH Verlag GmbH & Co.
