(c) The authors determined the C-C bond lengths and the Si-C-C bond angles in the acetylene ligand from the x- ray crystal structures of these two compounds. They also used IR to determine the stretching frequency of the C- C bond for the acetylene ligands. Their data for these two compounds, along with the data for the free, unbound acetylene ligand, are given in the table below. C-C bond length (Ả) Si-C-C Bond angle (deg) 179.2 C-C stretching frequency (cm) 2107 Compound Free, unbound bis(trimethylsilyl)acetylene Complex 1 Complex 2 1.208 1.225 169.4 1926 1854 1.243 150.6 Which complex do you think has stronger n back bonding with the Cu(I)? Be sure to explain your reasoning and justify it with the experimental data.
