New chiral organoantimony(III) compounds containing intramolecular N --> Sb interactions--solution behaviour and solid state structures.
Hypervalent organoantimony(III) compounds of the type [2-(Me2NCH2)C6H4]PhSbCl (1), [2-(Me2NCH2)C6H4]MesSbBr (7) and [2-(Me2NCH2)C6H4]nAr(3-n)Sb [n = 1, Ar = Ph (4), Mes (9); n = 2, Ar = Ph (5), Mes (10)] were prepared via salt elimination reactions between [2-(Me2NCH2)C6H4]Li and MesMgBr and PhnSbCl(3-n), [2-(Me2NCH2)C6H4]SbBr2 or [2-(Me2NCH2)C6H4]nSbCl(3-n) (n = 1, 2), in appropriate molar rat...
متن کاملNon-oxo vanadium(IV) alkoxide chemistry: solid state structures, aggregation equilibria and thermochromic behaviour in solution.
The reversible thermochromic behaviour of homoleptic [{V(OR)(4)}(n)] complexes in solution [R = Pr(i) (product I), Bu(s) (B(s)), Nep (N) and Cy (C)] is accounted for the existence of an aggregation equilibrium involving dimeric and monomeric species in which vanadium(iv) is respectively five- and four-coordinate. Bulky R groups such as Bu(t) and Pe(t) (tert-pentoxide) prevent aggregation and th...
متن کاملA study of the electrochemical behaviour of electrodes in operating solid-state supercapacitors
The electrochemical behaviour of electrodes and of complete solid-state supercapacitors has been studied by cyclic voltammetry (CV) and alvanostatic charge/discharge (CD) measurements using two independent electrochemical equipments. The first one controlled the execution of he test and recorded the voltage and current values of the complete supercapacitor while the other one recorded the poten...
متن کاملA Solid State Accelerator
We present a solid state accelerator concept utilizing particle acceleration along crystal channels by longitudinal electron plasma waves in a metal. Acceleration gradients of order 100 GV/cm are theoretically possible, but channeling radiation limits the maximum attainable energy to lo5 TeV for protons. Beam dechanneling due to multiple scattering is substantially reduced by the high accelerat...
