“…This reduction potential is exceptionally mild for silicon(IV), but in the range of electron-deficient boranes such as B(C 6 F 5 ) 3 . 61,62 Indeed, tetracoordinated silicon radical anions remain elusive as they are presumed to be powerful electron donors, even stronger than alkali metals. 63 A chemical reduction of 2 was attempted with decamethylcobaltocene (À1.9 V versus Fc/Fc + ) as a reducing agent to support the electroanalytical results.…”

Our Earth's crust is covered with compounds of silicon(IV). In each, tetracoordinated silicon(IV) arranges its four substituents in a tetrahedral fashion, while other environments are unknown. This work describes the isolation and properties of a molecular complex with square-planar silicon(IV). The flattened structural motif provokes a range of features that primes the second most abundant element for new applications in catalysis and materials science.

“…The formation of particulates, in conjunction with the decrease in voltammetric current, is consistent with existing reports of chlorate and chlorosiloxane formation when chlorosilanes are electrolyzed in the presence of ClO 4 − . 24,29 For solutions of Si 2 Cl 6 containing BPh 4 − at T = 90 °C, the solution changed color over the course of one hour. Although it is difficult to envision nucleophilic attack by BPh 4 − , (C 4 H 9 ) 4 N BPh 4 − can itself decompose near 100 °C.…”

The electrochemical reactivity and suitability of hexachlorodisilane and tetrakis(trichlorosilyl)silane as Si ec-LLS electrodeposition precursors in several electrolyte solutions have been investigated. Voltammetric data indicated that perchlorinated silanes exhibit mechanistically similar electrochemical responses as SiCl4, regardless of the Si–Si bond content in the precursor. The voltammetric responses were a strong function of the concentration of the precursor, indicating the participation of electrogenerated intermediates during the reduction and concomitant Si electrodeposition. Variation of the anion in the supporting electrolyte was found to be a critical factor for the thermal and chemical stability of the precursor bath. A combination of chronoamperometry and electron microscopy data were used to study the deposition efficiency specifically for hexachlorodisilane. The faradaic efficiency was low, regardless of overpotential or the composition of the electrolyte. Cumulatively, these data show that while larger chlorosilanes can be used for conventional Si electrodeposition over a wider range of conditions, their chemical instability and propensity for low faradaic efficiency limit their utility as reagents relative to SiCl4 for Si electrodeposition by ec-LLS.
