Abstract

[(tacn)₄Fe₄O₂(OH)₄] 2·8Br·9H₂O (tacn = 1,4,7-triazacyclononane), a tetranuclear iron(III) complex was synthesized by the hydrolysis of (tacn)FeCl₃ and crystallizes in the orthorhombic space group, Pca2(1), with cell parameters, a = 37.574(3) Å, b= 16.9245(12) Å, c = 14.2830(11) Å, V = 9082.9(12) Å³. [(tacn) ₄Fe₄O₂(OH)₄]⁴⁺ cations approach S₄ point symmetry containing an adamantane skeleton. Four Fe(III) atoms have distorted octahedral environments with two hydroxo and an oxo bridges. Two [(tacn)₄Fe₄O₂(OH) ₄]⁴⁺ clusters having different Fe⋯Fe distances are connected to each other by the networked hydrogen bonds. The electrochemical behavior reveals irreversible three cathodic and two anodic peaks. Magnetic properties are characterized by antiferromagnetic (AF) interactions between Fe(III) ion spins. However, the low-lying states are still magnetic and exhibit a blocking behavior and a magnetic hysteresis at low temperatures.
