Abstract

Abstract : We synthesized a mixed-valence tetranuclear complex and observed air oxidation-induced single-crystal-to-single-crystal transformation of the complex through oxidation of Fe(ii ) to Fe(iii ), deprotonation, and ligand exchange. Abstract : A mixed valence tetranuclear iron complex [(Hpmide)Fe II (NCSe)2 Fe III (pmide)]2 ·5CH3 OH (1) underwent oxidation and ligand exchange in the solid state (H2 pmide = N -(2-pyridylmethyl)iminodiethanol). Upon air oxidation, 1 was converted into [(pmide)Fe III (NCSe)Fe III (pmide)]2 (NCSe)2 ·2H2 O (2 ), which was accompanied by deprotonation and ligand exchange through a single crystal-to-single-crystal transformation.
