Another consequence is associated with the solvation pattern of Li4Cl4, influencing, in turn, its bonding properties. In CH3MgCl•Li4Cl4(THF)5 each metal is solvated by one THF, as in C4. On the contrary, in MgCl2•Li4Cl4(THF)7 , C5, both Mg and one of the Li's are solvated by two THFs. The three ionic Mg-Cl bonds favor higher solvation of Mg as previously reported, and accounts for its pentacoordination in C5. Furthermore, the electron-withdrawing character of MgCl2 weakens the Li-Cl interactions, cleaving another Li-Cl bond with the assistance of additional solvation at Li (Figure , Table ).
