摘要

A new cobalt alkoxide Co(C3H6O2) resulting from the reaction of cobalt acetate with 1,3 propanediol, exhibits a tetragonal structure that consists in a 3D framework of [Co4O4] cubanes connected to each other by double oxygen bridge in which all the Co(II) cations are five coordinated. This compound exhibits a 3D magnetic order below 36 K and combines exceptionally high magnetic anisotropy (coercivity higher than 4 T) with complex magnetic structure revealed by a spin flip at 13 T.
