摘要：

The dinuclear and trinuclear copper(II) complexes [Cu-2(L)(OH)(ClO4)(phen)(H2O)]ClO4 (.) [Cu-2(L)(OH)(ClO4)(2)(phen)(CH3OH)] (1) and [Cu-3(L)(2)(OH)(2)(H2O)(2)](NO3)(2) (2) (HL = 2-[2-(alpha-pyridyl)ethyl]imino-3-butanone oxime and phen = 1, 10-phenanthroline) were prepared and their crystal structures have been determined by X-ray crystallography. Complex 1 is composed of [Cu-2(L)(OH)(ClO4)(phen)(H2O)]ClO4 (1a) and [Cu-2(L)(OH)(ClO4)(2)(phen)(CH3OH)] (1b). In 1a and 1b, one oximato of L and one hydroxo group bridge two copper(II) ions. The linear trinuclear cation [Cu-3(L)(2)(OH)(2)(H2O)(2)](2+) in 2 is centrosymmetric, and one oximato and one hydroxo group bridge the central and terminal copper(II) ions. The strong antiferromagnetic interactions within the dinuclear and trinuclear complexes 1 and 2 have been observed (2J congruent to -900 cm(-1) for 1 and 2, respectively, H = -2JS(1).S-2).
