In this paper, the fractal dimensions are proposed for characterizing the optical fiber corrosion sensors, which is applied to measure the steel corrosion based on Fe-C alloy film. Because corrosion was a complex random phenomenon and the corrosion surface of Fe-C alloy film of the optical fiber corrosion sensor possessed fractal characteristics, the image fractal dimensions is as a quantitativ...

The anion [Fe(2)(S(2)C(3)H(6))(CN)(CO)(4)(PMe(3))](-) (2(-)) is protonated by sulfuric or toluenesulfonic acid to give HFe(2)(S(2)C(3)H(6))(CN)(CO)(4)(PMe(3)) (2H), the structure of which has the hydride bridging the Fe atoms with the PMe(3) and CN(-) trans to the same sulfur atom. (1)H, (13)C, and (31)P NMR spectroscopy revealed that HFe(2)(S(2)C(3)H(6))(CN)(CO)(4)(PMe(3)) is stereochemically ...

The asymmetric unit of the title complex, (C(12)H(9)N(2))(3)[Fe(CN)(6)]·C(2)H(5)OH·3H(2)O, consists of two half [Fe(CN)(6)](3-) anions located on inversion centers, three 1,10-phenanthrolin-1-ium cations, [Hphen](+), an ethanol and three water solvent mol-ecules. The average Fe-C and C-N bond lengths are 1.942 (6) and 1.154 (3) Å, respectively, while the Fe-C-N angles deviate slightly from line...

The title compound, [Fe(4)(C(5)H(5)OS)(2)S(CO)(12)], was prepared by the direct reaction of Fe(3)(CO)(12) and 2-furyl-methane-thiol in tetra-hydro-furan. Desulfurization took place readily to form an Fe(4)S(3) cluster. The mol-ecule consists of two similar [(μ-2-C(4)H(3)O-CH(2)S)Fe(2)(CO)(6)] moieties joined to a spiro-type four-coordinate μ(4)-S atom such that this bridging sulfur is tetra-hed...
