Graphical Abstract: Small and attractive: The proligand citric acid has been used to assemble a new anionic hexanuclear cobalt(II) cluster (see picture). The complex displays single-molecule magnet (SMM) behavior, with an energy barrier to the reorientation of magnetization of 26 K, the highest value to have been recorded for a non-manganese based SMM.
