Solvent-modulated metamagnetism in an Fe(II) system exhibiting a two-step field-induced magnetic transition

Dalton Trans. 2012 May 21;41(19):5912-8. doi: 10.1039/c2dt12260j.

Abstract

A one-dimensional iron(II) coordination polymer, [Fe(3)(hpdc)(2)(H(2)O)(6)]·2H(2)O (H(3)hpdc = 2-hydroxypyrimidine-4,6-dicarboxylic acid) has been synthesized and characterized. The compound exhibits field-induced two-step magnetic phase transitions and a coexistence of spin-canting and metamagnetism, and undergoes a structural transformation from single-crystalline to amorphous state upon dehydration, accompanied by significantly enhanced spontaneous magnetization and critical temperature.
