Abstract

One electron decides whether the coordination of tetrazolenol ligands (HL) with Fe ions leads to the mononuclear complex [FeL3] (FeIII) or the three‐dimensional coordination polymer [(FeL2)n] 1 (FeII). A representationof 1 is shown (right) along with its “monomer”. The linkage occurs by coordination of the CN groups. The crucial test supporting a polymeric structure for 1 was provided by Mössbauer spectroscopy. At 1.6 K a weak antiferromagnetic ordering arises, which can be attributed to cooperative spin‐spin exchange processes. R = Me3CCH2. (Figure Presented.)
