Abstract: A new carboxylate complex [Co<subscript>2</subscript>Li<subscript>2</subscript>(Piv)<subscript>6</subscript>(L)<subscript>2</subscript>]·CH<subscript>3</subscript>CN (1) (Piv is the anion of pivalic acid) has been synthesized and structurally characterized. According to ac magnetic measurements, compound 1 exhibits a field induced slow magnetic relaxation, which is approximated by a combination of Raman and direct mechanisms. These data are confirmed by ab initio calculations indicating easy-plane anisotropy of Co(II) ions in the complex. [ABSTRACT FROM AUTHOR]
