Hexakis(μ2-2-aminoethanethiolato)triiron(III) tris(perchlorate)

چکیده
In the title salt, [Fe(3)(C(2)H(6)NS)(6)](ClO(4))(3), the trinuclear cation lies on a special position of site symmetry; the central Fe atom is coordinated by six thiol-ate groups from the two flanking fac-(S)-[Fe(C(2)H(6)NS)(3)] units. In the flanking units, the three C(2)H(6)NS groups each chelate to the metal atom. The cations inter-act with the perchlorate anions through weak N-H⋯O hydrogen bonds resulting in a three-dimensional network. In the asymmetric unit two cations are present, one of which is disordered over two positions with occupancies of 0.75 and 0.25.

Chemistry at the protein-mineral interface in L-ferritin assists the assembly of a functional (μ3-oxo)Tris[(μ2-peroxo)] triiron(III) cluster.
X-ray structures of homopolymeric L-ferritin obtained by freezing protein crystals at increasing exposure times to a ferrous solution showed the progressive formation of a triiron cluster on the inner cage surface of each subunit. After 60 min exposure, a fully assembled (μ3-oxo)Tris[(μ2-peroxo)(μ2-glutamato-κO:κO')](glutamato-κO)(diaquo)triiron(III) anionic cluster appears in human L-ferritin....

In the title compound, [Mn3(C14H12ClN2O)3(CH3O)3O]ClO4·1.1CH2Cl2·0.9C4H10O, the cation consists of a central Mn3O core with μ2-methano-late bridging between adjacent MnIII atoms, thus giving each MnIII atom a mer-O3 coordination environment. Six-coordination for each MnIII atom is provided by the deprotonated Schiff base ligand (E)-4-chloro-2-({[2-(pyridin-2-yl)eth-yl]imino}-meth-yl)phenolate. ...
متن کاملSynthesis and characterization of a tris(2-hydroxyphenyl)methane-based cryptand and its triiron(III) complex.
Reaction of tris(5-amino-2-ethoxy-3-isopropylphenyl)methane and pyridine-2,6-dicarbonyl-dichloride affords a multi-dentate cryptand in 48% yield. Metallation with iron(III) chloride results in a substantial conformational change of this ligand to give a trianionic triiron(III) complex. Ferric cations line the periphery of the internal cavity with each adopting a square pyramidal N(3)Cl(2) coord...

In the title complex, {[Tb(C(6)H(5)NO(2))(3)(H(2)O)(2)](ClO(4))(3)·H(2)O}(n), the Tb(III) ion is coordinated by six O atoms from six isonicotinate (inic) ligands and two water mol-ecules, displaying a bicapped trigonal-prismatic geometry. The inic ligands, which are protonated at the pyridine N atom, link the metal centres, forming a polymeric chain running parallel to the a axis. The chains ar...

The asymmetric unit of the title compound, [Fe(3)(CH(3)COO)(6)O(H(2)O)(3)]NO(3)·CH(3)COOH, consists of a hexa-μ(2)-acetato-triaqua-μ(3)-oxo-triiron(III) macrocation, a nitrate ion and an acetic acid solvent mol-ecule. In the cation, each Fe(3+) ion is coordinated by four carboxyl-ate O atoms, one central bridged O atom and one water mol-ecule, resulting in distorted FeO(6) octa-hedra. A network...
