Abstract:
The binding mode and relative position of tripodal ligands influence the charge distribution in Lindqvist-type vanadium alkoxides. The stronger the delocalization of d-electrons is decreased, the further shifted are the observed redox events to higher potentials. X-ray crystallographic data of different {VIV/V 6(tripod)2} structures is evaluated, and valence sum calculations are used to assign oxidation states to chemically inequivalent vanadium positions in such hexanuclear aggregates. The impact of varying the charge distribution in {VIV/V 6} species is discussed by comparing reduction potentials derived from voltammetric experiments. In this way, a new group of {VIV/V 6(tripod)2} isomers is characterized and related to known cis- and trans-{VIV/V 6(tripod)2} isomers.

Van der Waals Equation
First, the attractive forces between molecules, which are stronger at higher densities and reduce the pressure, are considered by adding to the pressure a term equal to the square of the molar density multiplied by a positive coefficient a. Second, the volume...
Acid Halides to Alcohols: LiAlH4 Reduction
The mechanism proceeds in three steps. First, the nucleophilic hydride ion attacks the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs as a leaving group, generating an aldehyde. A second nucleophilic attack by the hydride yields an alkoxide ion, which, upon protonation, gives a primary alcohol as...
