  allotropic form of elemental silicon. Similarly, the analogous Ge(II)→Ba complex 9, upon decomposition, forms tetragonal germanium, a dense and rare allotrope of elemental germanium. The energetics of this unprecedented alkaline-earth-metal-induced liberation of elemental silicon and germanium was additionally studied by DFT methods, revealing that the transformations are pronouncedly exergonic and considerably

• Synthesis and Structure of N-Heterocyclic Carbene Complexes of Germanium(II)

  The synthesis and structural characterization of a series of N-heterocyclic carbene (NHC) complexes of GeR1R2 are reported, where R-1 = R-2 = Mes (Mes = 2,4,6-trimethylphenyl) (1), R-1 = R-2 = F (5), R-1 = R-2 = Br (6), R-1 = Cl, R-2 = OTf (OTf = O3SCF3) (7), R-1 = R-2 = (OBu)-Bu-t (10), and R-1 = R-2 = NCS (11). The bond length between the carbenic carbon and the germanium is observed to vary in accordance with the pi-donating ability of the substituent on Ge. Efforts to synthesize stable complexes with small alkyl or aryl substituents were not successful; evidence for oligomerization of the GeR2 fragment is presented. The reaction between 1 and 3 (R-1 = R-2 = Cl) resulted in the formation of an NHC-coordinated germylgermylene (13). The H-1 NMR spectra of 3-7, 10, and 11 display broad signals at room temperature. To rationalize the H-1 NMR spectra, mechanisms for conformational interchange, as well as intermolecular exchanges, are discussed.
