Original language description
The design and synthesis of a Schiff base H2L, (2-{[(2-hydroxy-3-methoxybenzyl)imino]methyl)phenol), bearing an ONOO donor set has been explored for its reactivity pattern with LnCl(3)center dot 6H(2)O (Ln = Gd-III and Dy-III) and Ni(CH3CO2)(2)center dot 4H(2)O in the presence of NEt3 for molecular aggregation. Coordination driven spontaneous self-assembly reactions provide (Gd2Ni6L4(mu(3)-OH)(6)(mu-OH)(2)(CH3CO2)(2)(mu-H2O)(2)(H2O)(3)(MeOH)]center dot 8H(2)O (1) having a 'butterfly-shaped' core and [Dy2Ni6L4(mu(3)-OH)(4)(mu-Cl)(2)Cl-4(H2O)(2)(MeOH)(2)]center dot 2MeOH center dot 4H(2)O (2) with a 'candy-shaped' core. Fusion of six partial cubane units led to a mineral-like core in 1, developed around the central Ni-2(OH)(2) moiety, whereas in the case of 2, four such partial cubanes collapsed on Dy-2(OH)(2). Direct-current (dc) magnetic susceptibility measurements revealed that predominant ferromagnetic interactions lead to a high-spin S = 13 ground state for 1. Complex 2 exhibits slow relaxation of magnetization under an applied small dc field with an energy barrier to reorientation of the magnetization, U-eff = 19.3 K. The static and dynamic magnetic data are analysed and corroborated by density functional theory (DFT) and detailed CASSCF based calculations.
