Chemistry of the Carba-closo-dodecaborate(−) Anion, CB11H12-

“…In Cu(CO) 2 (1-Bn-CB 11 F 11 ), Cu coordinates to the benzene ring and not to the fluorine atoms of the carborate . The C-alkyl carboranes 2 and 17 form silver complexes (η 2 -C 6 H 6 )Ag( 2 ) 44 and Ag( 17 ) .…”

“…Several silver, , molybdenum, copper, and rhodium complexes 137 show no interaction between the cation and the carborate anion. Different cationic metal complexes of 1-alkyl-CB 11 F 11 - have been isolated, including Ag, Cu, and Rh derivatives. , No coordination of the cation to the fluorinated carborate was observed.…”

Germylene Energetics: Electron Affinities and Singlet−Triplet Gaps of GeX2 and GeXY Species (X, Y = H, CH3, SiH3, GeH3, F, Cl, Br, I)

“…Germylenes, divalent germanium compounds − GeR 2 , have evolved over the past 20 years from exotic reaction intermediates to important chemical species. − The progress in this field over the past 5 years is particularly impressive. − A spectacular, very recent example is the use of germylene methodology to synthesize an encapsulated germanium(II) dication . Moreover, the increasing importance of plasma etching and deposition processes plays a significant role in the production of high-performance microelectronics products and thus has necessitated detailed knowledge of the species involved in these processes.…”
