We present the first ferromagnetically-coupled Er(3+) complex with linked, high-anisotropy Er-COT (COT(2-) = cyclooctatetraene dianion) subunits. The dinuclear complex, [Er(μ2-Cl)(COT)(THF)]2, demonstrates single-molecule magnetism with a single, zero-field magnetization relaxation barrier of Ueff = 113 cm(-1). This system offers evidence that anisotropy can be preserved in the presence of ferromagnetic linking of the Er-COT subunits, providing a rational means to build strong molecular magnets of tunable dimensionality.
