The mol-ecular framework of the title compound, C(11)H(6)I(2)OS(8), is almost planar [maximum deviation = 0.057 (5) Å] except for the two methyl-sulfanyl groups, which are twisted relative to the mol-ecular skeleton, with C-C-S-C torsion angles of 49.74 (22) and 82.91 (21)°. In the crystal, mol-ecules are stacked alternately in opposite orientations, forming a one-dimensional column along the b...

In 1937, a component of potato extract, named “potato growth factor”, was discovered to be necessary for the growth of Lactobacillus (1). Subsequent work by a number of laboratories led to the isolation and purification of the active compound in 1951 (2). The compound was identified as α-lipoic acid (LA; formerly referred to as thioctic acid), an eight-carbon dithiol containing a single chiral ...

Using density functional theory and the Bardeen, Tersoff, and Hamann formalism we have calculated spin-polarized electron transport in a system involving a nonbonded magnetic probe tip and a self-assembled monolayer SAM of benzene-1,4-dithiol on a Ni 111 substrate. A significantly higher tunneling current is obtained for a configuration in which the spin of the probe tip is aligned parallel to ...
