✦ Synopsis

Abstract

The synthesis and magnetic behavior of four new dinuclear iron(II) complexes Fe~2~2a‐d × 4Py with the iron in an octahedral coordination sphere is presented in this paper. The complex c is a high‐spin complex over the whole temperature range investigated, while the complexes a,b, and d perform a partial low‐spin ⇔︁ high‐spin spin transition. In case of Fe~2~2b × 4Py, X‐ray structure analysis of the HS/LS state was possible, showing that in one molecule both iron centers are either in the low‐spin or sin the high‐spin state. © 2005 Wiley Periodicals, Inc.
