Polynuclear complex family of cobalt(II)/sulfonylcalixarene: one-pot synthesis of cluster salt [Co14(II)]+[Co4(II)]- and field-induced slow magnetic relaxation in a six-coordinate dinuclear cobalt(II)/sulfonylcalixarene complex.

In this paper, we report the synthesis and description of a new family of polynuclear cobalt(II) complexes. Starting from the same initial compounds but varying the reaction time results in the formation of several new clusters, an original structure based on [Co14][Co4] clusters was obtained, representing the first one-pot synthesis of a cobalt aggregate salt reported in the literature. The synthesis and magnetic properties of these cobalt compounds are discussed. Three of them display a binuclear molecular structure (1-3) with two encapsulated Co(II) ions and show slow relaxation of magnetization at small applied magnetic field (Ueff = 10.7 K for 2 and Ueff = 20.3 K for 3), a characteristic of single-molecule-magnet materials.
