Group 13 amides heterometallic

An important class of alkali and alkaline earth metal amides are Mulvey s inverse crown complexes (also discussed in Chapter 2, dealing with sodium and potassium amides), in which cationic homo- or heterometallic macrocycles are hosts to anionic guest moieties.The term inverse crown indicates that the Lewis acidic/Lewis basic sites are reversed or exchanged in comparison to conventional crown ether complexes. Scheme 3.9 illustrates the range of recently published alkali and alkaline earth metal amide inverse crown complexes (for related Zn species see Chapter 7 on group 12 amides). [Pg.56]

The amide products do not have the anticipated symmetrical structure, instead one MMe3 group does not form a /i-methyl bridge. Reaction with excess MMea gives heterometallic peralkyls... [Pg.110]
