Abstract

A hexanuclear Fe(III) compound with new core topology, [Fe₆(OMe)₂(DHMP)₄(AD)₂] (1, H₃DHMP = (E)-2-((1,3-dihydroxy-2-methylpropan-2-ylimino)methyl)phenol, H₂AD = adipic acid), is reported. The hexanuclear Fe(III) core can be viewed as two Fe₃(DHMP)₂ units connected through double μ₂-OMe^- bridges, featuring adjacent Fe···Fe distances of 3.105 and 3.109 Å within unit and 3.111 Å between units, respectively. Variable temperature magnetic studies indicate antiferromagnetic exchanges between adjacent Fe(III) ions and which mediated by μ₂-OMe^- bridges is stronger than those by DHMP alkoxo bridges. Magnetic-structural correlation is also proposed.
