The 3-coordinate 12 VE iron(II) benzyl complex [(nacnac)-Fe(CH2Ph)] reacts with B(C6F5)3 to yield a paramagnetic contact ion pair with an eta 2-(o,m)-[PhCH2B(C6F5)3] anion, which was characterised by X-ray diffraction.

In an investigation concerned with the solubilization and characterization of membrane-bound iron-sulfur proteins of photosynthetic bacteria, succinate dehydrogenase was solubilized from Rhodospirillum rubrum chromatophores by the detergent lauryl dimethylamine oxide (LDAO) or by an alkaline washing treatment. The LDAO-solubilized enzyme was purified by a combination of DEAE-cellulose and Sepha...
