Isostructural bridging diferrous chalcogenide cores [Fe II (μ-E)Fe II ] (E = O, S, Se, Te) with decreasing antiferromagnetic coupling down the chalcogenide series

Isostructural bridging diferrous chalcogenide cores [Fe II (μ-E)Fe II ] (E = O, S, Se, Te) with decreasing antiferromagnetic coupling down the chalcogenide series

Ferrous bridging mono-chalcogenide ate complexes K2[(tBupyrpyrr2)Fe2(μ-E)] (2-E) (E = O, S, Se, and Te) are prepared and show a Fe–E–Fe bridge from linear (E = O) to acute for E = Te, with lesser antiferromagnetic coupling going down the series.
