چکیده

Under solvothermal conditions the unprecedented nonanuclear Fe(III) aggregate [Fe9(mu3-O)4(mu-OH)4(hpdta)4]5- is formed through the formal encapsulation of [Fe(H2O)6]3+ by four [Fe2(hpdta)(H2O)2]+ units: the aggregates have ground state spins of S= 13/2 while the observed hysteresis below 1.8 K results from inter-cluster antiferromagnetic coupling.

Aggregation of dinuclear {Fe2hpdta} units to form polynuclear oxy/hydroxy-bridged Fe(III) coordination complexes.

An approach for the preparation of oxy/hydroxy briged Fe(III) clusters that takes advantage of hydrolytic condensations of well defined {Fe(2)hpdta(H(2)O)(4)} building units is presented. Co-ligands such as tripodal H(3)tea or bidentate organic bases such as ethylenediamine (enH(2)) can be used to complete the coordination spheres of the Fe(III) centres and stabilise unsymmetrical iron-oxo clus...

Kinetics and mechanism of the oxidation of sulfur(IV) by iron(III) at metal ion excess†

The kinetics and mechanism of the reaction between iron() and sulfur() was studied at high iron() excess at 10.0 and 25.0 C in 1.0 M NaClO4 by the stopped-flow method. The number of absorbing species in this system was determined by matrix rank analysis of time-resolved spectra. The reaction exhibits composite kinetic features which could be explained by considering the reactions of Fe(...

Synthesis and characterisation of Fe6 and Fe12 clusters using bicine

Reaction of bicine {BicH3, N,N-bis(2-hydroxyethyl)glycine} with an Fe(III) oxo-centered pivalate triangle in MeCN in the presence of Et2NH yields [Et2NH2]2[Fe6O2(OH)2(Bic)2(O2CCMe3)8], which possesses an S = 5 ground state. Changing the base to NaOMe produces [Fe12O4(Bic)4(HBic)4(O2CCMe3)8], which contains two Fe6 units bridged by the carboxylate arms from the bicine ligands. The complex displa...
