Alkaline earth metal complexes organometallic

There is also an extensive organometallic chemistry of the alkali and alkaline earth metals. Many of these compounds, particularly those of Li, Be and Mg, form coordination complexes with appropriate donor ligands. This topic has been recently surveyed in the companion volume Comprehensive Organometallic Chemistry and so only apposite references will be included here.32... 

This chapter will concentrate on the chemistry of metal-14-centered anions (Ge, Sn, Pb). These compounds and their silyl analogues are ionic or polarized alkaline and alkaline earth metal-14 compounds, as well as delocalized molecules such as metalloles. Ammonium metallates Mi4 R4N+ or metal-14-centered anion radicals are also considered. The subject was explored during the 1960s and 1970s and thoroughly reviewed in 1982 and 1995 in Comprehensive Organometallic Chemistry, Vols. I and and for silicon species in a previous volume of this series . By that time the main routes to metal-14 anions were known. Since then, the subject has been developed in the topics of particular syntheses, stabilization using steric hindrance, electronic effects and complexation, spectroscopic and structural analyses "...

A category of organometallic alkahne earth complexes does not involve metal hgand bonding. Such compounds, while common in aqueous solution for many cations, are much less prevalent for the alkaline earth organometallics. Nonetheless, under carefully controlled reaction conditions these highly reactive compounds may be synthesized, isolated, and characterized. In order to accomplish this feat, both the anion and the cation must be appropriately stabilized. A combination of two factors should be considered when attempting to induce...
