Group 11 metal (Cu, Ag and Au) amides have proven to have numerous applications in chemistry, some of which are in the areas of nanocrystal synthesis, atomic layer deposition and electronics.[1] Of particular interest is the apparent philicity that the metal centers have to one another. Such interactions lead to otherwise inexplicably short metal-metal distances and interesting molecular geometries.[2] The isolation of five novel metal amido complexes (1 – 5) is described herein. Complexes 1 and 2 were found to exist in the solid-state as planar tetranuclear Cu clusters with alternating dimethylamido (1) or benzamidinate (2) and bis(trimethylsilyl)amido ligands. Complexes 3, 4 and 5 were synthesized using the lithium silylamide generated via the addition of n-butyl lithium to a solution of 1,3-diphenyl-1,1,3,3-tetramethyldisilazane. The lithium amide was subsequently reacted with the corresponding metal (Cu (3), Ag (4) and Au(5)) salt to yield air and light sensitive tetranuclear complexes. Complex 3 was found to contain alternating bis(dimethylphenylsilyl)amide and 1,1-diethyl-3,3-dimethylguanidinate ligands. All five complexes were isolated through evaporation to produce colorless crystals. The compounds were fully characterized using single crystal x-ray diffraction, FT-IR, 1H and 13C NMR. The use of these complexes as precursors for nanocrystals was also investigated. [1] McCain, M. N.; Schneider, S.; Salata, M. R.; Marks, T. J. Inorg. Chem. 2008, 47, 2534-2542. [2] Tsipis, A.
