Isostructural Bridging Diferrous Chalcogenide Cores [FeII(µ-E)FeII] (E = O, S, Se, Te) with Decreasing Antiferromagnetic Coupling Down the Chalcogenide Series

Iron compounds containing a bridging oxo or sulfido moiety are ubiquitous in biological systems, but substitution with the heavier chalcogenides selenium and tellurium, however, is much rarer, with only a...
