Resumen

The hybrid organo-inorganic compounds [Cu4(bipy)4V4O11(PO4)2]nH2O (n ∼ 5) (1), [Cu2(phen)2(PO4)(H2PO4)2(VO2) · 2H2O] (2) and [Cu2(phen)2(O3PCH2PO3)(V2O5) (H2O)]H2O (3) which present different bridging forms of the phosphate/phosphonate group, show different bulk magnetic properties. We herein analyze the magnetic behaviour of these compounds in terms of their structural parameters. We also report a theoretical study for compound (1) assuming four different magnetic exchange pathways between the copper centres present in the tetranuclear unit. For compound (1) the following J values were obtained J1 = +3.29; J2 = -0.63; J3 = -2.23; J4 = -46.14 cm-1. Compound (2) presents a Curie-Weiss behaviour in the whole range of temperature (3-300 K), and compound (3) shows a maximum for the magnetic susceptibility at 64 K, typical for antiferromagnetic interactions. These data where fitted using a model previously reported in the literature, assuming two different magnetic exchange pathways between the four copper(II) centres, with J1 = -30.0 and J2 = -8.5 cm-1.
