✦ Synopsis

Abstract

The dinuclear iron(II) complex {[Fe(CH~3~bipy)(NCS)~2~]~2~bpym} has been synthesised and its crystal structure determined at 293 K. The magnetic properties display intramolecular antiferromagnetic coupling at 1 bar (J = −4.2 cm^−1^), and the onset of a pressure‐induced spin conversion is observed at 11 kbar. Magnetic field Mössbauer measurements have been carried out at 4.2 K, and indicate that the HS species correspond to [HS‐HS] pairs. (© Wiley‐VCH Verlag GmbH & Co.
