A tale of two studies: Syntheses of silicon nitride chemical vapor deposition precursors and divalent lanthanide N,N-dimethylaminodiboranate complexes
… molecular structures of new SmII and TmII N,N-dimethylaminodiboranate (DMADB) complexes. Treatment of solutions of SmI2(thf)2 in thf with Na(H3BNMe2BH3) results in the formation of Sm(H3BNMe2BH3)2(thf)3 which can be readily converted to the dimethyoxyethane (dme) adduct, Sm(H3BNMe2BH3)2(dme)2 …

Aminodiboranates: syntheses, structures, and applications for chemical vapor deposition
… reaction ThCl₄ with 4 equivalents of sodium N,N-dimethylaminodiboranate, Na(H₃BNMe₂BH₃), in tetrahydrofuran produces the new complex Th(H₃BNMe₂BH₃)₄. The thorium center forms bonds with fifteen hydrogen atoms; accordingly, this is the first example of a fifteen-coordinate atom of any kind. As …

Divalent transition metal centers: the synthesis of new chemical vapor deposition precursors and studies of ethylene polymerization and oligomerization catalysts
… complexes of the chelating borohydride, N,N-dimethylaminodiboranate (DMADB). To date, attempts to synthesize homoleptic complexes of the late transition metals have afforded intractable mixtures, likely the result of overreduction of the metal center. This work has focused on the synthesis …

High coordination number compounds of thorium borohydride, and of calcium and strontium N,N-dimethylaminodiboranates
… (M = Ca or Sr) with two equiv. of sodium N,N-dimethylaminodiboranate, Na(H3BNMe2BH3) in Et2O at 0 ºC give a product which, after being dried in vacuum, proves to be the compound M(H3BNMe2BH3)2. Before they are dried in vacuum, the colorless crystals obtained from the above reaction consist as …

Volatile metal borohydride complexes: synthesis and characterization of new chemical vapor deposition precursors
… by Keller for the synthesis of sodium N,N-dimethylaminodiboranate. Implementing this method, the sterically bulky aminodiboranates: sodium N-isopropyl-N-methylaminodiboranate, sodium N,N-diisopropylaminodiboranate, sodium cis-2,6-dimethylpiperidinyldiboranate, sodium …

Chemical approaches to the improved performance of nanoelectronic devices
… has synthesized a series of lanthanide tris(N,N-dimethylaminodiboranate) (Ln(dmadb)3) complexes and demonstrated their utilization as Ln2O3 CVD precursors. The mechanism of the salt elimination reaction that generates Nd(dmadb)3 was examined by 11B NMR spectroscopy. We found that the treatment of …
