The Si₂H radical supported by two N-heterocyclic carbenes.

ABSTRACT: Cyclic voltammetric studies of the hydridodisilicon(0,II) borate [(Idipp)(H)Si^II[double bond, length as m-dash]Si⁰(Idipp)][B(Ar^F)₄] (1H[B(Ar^F)₄], Idipp = C[N(C₆H₃-2,6-iPr₂)CH]₂, Ar^F = C₆H₃-3,5-(CF₃)₂) reveal a reversible one-electron reduction at a low redox potential (E _1/2 = -2.15 V vs. Fc⁺/Fc). Chemical reduction of 1H[B(Ar^F)₄] with KC₈ affords selectively the green, room-temperature stable mixed-valent disilicon(0,I) hydride Si₂(H)(Idipp)₂ (1H), in which the highly reactive Si₂H molecule is trapp
