A new trinuclear copper(II) complex, [Cu-3(patrz)(10)(H2O)(2)](ClO4)(6). 2CH(3)OH (patrz = 4-(isopropylamino)-1,2,4-triazole), has been prepared and structurally determined. This complex represents the first structurally characterized linear trinuclear Cu(II) complex containing triple mu -N-1,N-2-1,2,4-triazole bridges and showing weak ferromagnetic interaction (J = 1.99 cm(-1)) between adjacent Cu(II) ions. The central Cu(II) ion is located on an inversion center and linked to each of the external Cu(II) ions by means of triple mu -N-1, N-2-1,2,4-triazole bridges with a Cu-Cu separation of 3.853 Angstrom. The best fitting for the experimental data gives J = 1.99 cm(-1); the nature and magnitude of the ferromagnetic exchange is preliminarily discussed on the basis of its structure.
