Synthesis and structure of [[MeAl(mu-PMes)(PMes)]2Li4]2 x 7thf, containing a [MeAl(mu-PMes)(PMes)]2(4-) tetraanion (Mes = 2,4,6-Me3C6H2).
The reaction of MeAlCl2 with MesPHLi (1:4 equivalents) in thf/toluene gives the cage complex [[MeAl(mu-PMes)(PMes)]2Li4]2 x 7thf (1), containing an [[MeAl(mu-PMes)(PMes))2]4- tetraanion which is valence-isoelectronic with extensively studied Group 15 anions of the type [E(mu-NR)(NR)]2(2-).
