Dihydrogen Binding to Isostructural S = 1/2 and S = 0 Cobalt Complexes
Two isostructural, nonclassical Co (H2) complexes are prepared from their Co (N2)
precursors using tris (phosphino) silyl and tris (phosphino) borane ancillary ligands.
Comproportionation of CoBr2 and Co metal in the presence of TPB (tris-(o-
diisopropylphophinophenyl) borane) gives (TPB) CoBr (4). One-electron reduction of 4
triggers N2 binding to give (TPB) Co (N2)(2-N2) which is isostructural to previously reported
[SiP3] Co (N2)(1-N2)([SiP3]= tris-(o-diisopropylphosphinophenyl) silyl). Both 1-N2 and 2-N2 …
