摘要：

Bridging μ3‐oxo and μ2‐hydroxo ligands characterize the structure of the cluster anion 1, which can be prepared as a highly soluble K or Na salt in water. The structure of 1 can be viewed as two parallel, μ3‐oxo‐bridged Fe3 triangles joined by μ‐hydroxo bridges or as two Fe4 butterfly structures with shared wing tips. Cluster 1 has more short FeFe separations than all other related compounds, and its effective magnetic moment μeff increases dramatically at low temperatures. This magnetic behavior is not completely understood. (Formula Presented.) Copyright © 1993 by VCH Verlagsgesellschaft mbH, Germany
