Written by internationally recognised leaders in the field, Metal Amide Chemistry is the authoritative survey of this important class of compounds, the first since Lappert and Power’s 1980 book “Metal and Metalloid Amides.” An introduction to the topic is followed by in-depth discussions of the amide compounds of: alkali metals alkaline earth metals zinc, cadmium and mercury the transition metals group 3 and lanthanide metals group 13 metals silicon and the group 14 metals group 15 metals the actinide metals Accompanied by a substantial bibliography, this is an essential guide for researchers and advanced students in academia and research working in synthetic organometallic, organic and inorganic chemistry, materials chemistry and catalysis.

Research has been directed towards the development of organonitrogen-magnesium chemistry, focusing on amide ligands mainly, and on amidinide ligands to a lesser extent. New compounds have been characterised by elemental analyses and NMR spectroscopic studies and seventeen of them have been crystallographically authenticated by X-ray diffraction. Within the area of dianionic ligands, it has been found that deprotonating 1,8-diaminonaphthalene twice with dibutylmagnesium leads to [{(1,8-C10H6(NH)2)Mg.HMPA}3.2THF], the first magnesium amide trimer, having an unprecedented N6Mg3 cage structure. In contrast, treating the diamines N,N'diphenylethylenediamine or N,N' -dibenzylethylenediamine with the same reagent in the same stoichiometry produces [{MgN(Ph)CH2CH2N(Ph).2THF(1.5THF)}2], [{MgN(CH2Ph)CH2CH2N(CH2Ph).HMPA}2], or [MgN(Ph)CH2CH2N(Ph).2HMPA], which adopt more conventional dimeric ring or monomeric structures. Also, the novel magnesium aluminate salt, [Mg(HMPA)4.2AlMe4], has been synthesised serendipitously from an attempt to make a mixed-metal diamide complex. Within the area of monoanionic ligands, two structurally related mixed lithium-magnesium amides, [{(Me3Si)2N}13LiMg] and [{(c-C6H11)2N}3LiMg.THF], based on discrete (NLiNMg) cyclic cores, have been prepared. Further exploration of the hexamethyldisilazide has opened up a remarkable new area of macrocyclic chemistry. Thus, magnesium-substituted derivatives of classical alkali metal amide ring structures, [{(Me3Si)2N}4Li2Mg2(02)x(O)y] and [{(Me3Si)2N}4Na2Mg2(02)x(O)y], having oxo or peroxo core dianions for charge balance, have been established. The tetramethylpiperidide analogue, [{Me2CCH2CH2CH2(Me)2CN}4Li2Mg2(O)], has also been made. In an extension of this work, a larger twelve-membered (N6Na4Mg2)2+ cationic ring system have been realised through [{Me2C(CH2)3(Me)2CN}6Na4Mg2{C6H3(CH3)}] and [{Me2C(CH2)3(Me)2CN}6}Na4Mg2(C6H4)}]. This ring acts as a templating host for the selective di-deprotonation of toluene and benzene respectively, the dianions of which occupy the ring centre. Possible insight into the mechanism of arene incorporation in these macro cycles is gained through the structure of [{(Me3Si)2N}6K2Mg2.4{C6H5(CH3)}], the first potassium amido magnesate species. Finally, two magnesium and one lithium-magnesium amidinide structures, [{PhNC(Ph)NPh}2Mg.2DMSO,C6H5CH3] [{PhNC(Ph)NPh}2Mg.2HMPA,C6H5CH3] and [{PhC(NSiMe3)2}4Li4Mg(O)] respectively, have been reported.

This book is devoted to general questions of the chemistry of metal alkoxides – including physiochemical properties, structure, specific features of single groups of alkoxides, theoretical principles of their use, and major applications of this method in the preparation of functional materials.
