AbstractIn the present work, coordination possibilities of the system dapdoH2/Ni2+, being dapdoH2 = 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 [Ni2(dapdo)2] (1), [Ni3(OH)(BzO)3(dapdo)(dapdoH2)(H2O)]·1.25H2O (2), [Ni3(AcO)4(dapdoH)2(H2O)2]·H2O (3), and [Ni4(AcO)3(dapdo)(dapdoH)2(H2O)3]·(AcO)·3H2O (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).
