Abstract
Reaction of Co(II) with phenylcinnamic acid and sodium hydroxide under hydrothermal conditions yields a new hexanuclear Co(II) complex, [Co6(OH)2(L)10] (L = phenylcinnamate). [Co6(OH)2(L)10] consists of two edge-sharing octahedral {CoO6} and four tetrahedral {CoO4} units linked through μ-carboxylate ligands and μ-hydroxide ions. The magnetic moment shows a large decrease from 300 to 25 K which amounts to antiferromagnetic coupling between cobalt ions in octahedral and tetrahedral sites leading to an s = 3 ground-state at low temperatures.
