Abstract/OtherAbstract:
In the present work, coordination possibilities of the system dapdoH(2)/Ni(2+), being dapdoH(2) = 2,6-diacetylpyridine dioxime, have been explored, offering as a result a number of unprecedented clusters with a variety of topologies and magnetic behaviors. Depending on the precursors and reaction conditions, several compounds named [Ni(2)(dapdo)(2)] (1), [Ni(3)(OH)(BzO)(3)(dapdo)(dapdoH(2))(H(2)O)] x1.25 H(2)O (2), [Ni(3)(AcO)(4)(dapdoH)(2)(H(2)O)(2)] x H(2)O (3), and [Ni(4)(AcO)(3)(dapdo)(dapdoH)(2)(H(2)O)(3)] x (AcO) x 3 H(2)O (4) were achieved and structurally well-characterized. Dc magnetic measurements were carried out in the 2-300 K range revealing antiferromagnetic interactions for (2-4) compounds and diamagnetic response for the square planar coordinated complex (1).
