MAGNESIUM ANTHRACENE SYSTEMS - 10 - NANOCRYSTALLINE ZINTL PHASES FROMMAIN-GROUP METAL CHLORIDES AND MAGNESIUM ANTHRACENE OR ACTIVATED MAGNESIUM

Ga, Tl, Sn, Pb, As, Sb, Bi, Cd, and Hg chlorides react with magnesium anthracene.3 THF (MgA), anthracene-activated magnesium, or ''active ma gnesium'' (Mg) in THE generating the respective Mg intermetallics in a nanocrystalline or amorphous state (Eqs. 1-3). Mg intermetallics acc essible through the wet-chemical route can be exploited by metathetica l exchange reactions for the preparation of other, highly active inter metallics and alloys; EXAFS investigation of X-ray amorphous Cu-Sn and Pd-Pb solids thus prepared (Eqs. 13 and 14) shows that they are true bimetallic alloys (solid solutions).
