Neutral and anionic silicon clusters (siliconoids) are regarded as important model systems for bulk silicon surfaces. For 25 years their formation from binary alkali metal silicide phases has been proposed, but experimentally never realized. Herein t

Polyanionic silicon clusters are provided by the Zintl phases K4 Si4 , comprising [Si4 ]4- units, and K12 Si17 , consisting of [Si4 ]4- and [Si9 ]4- clusters. A combination of solid-state MAS-NMR, solution NMR, and Raman spectroscopy, electrospray io

Molecules with low-valent Ge atoms are generally synthesized from organohalogen germanes as precursors. The Zintl phase K4Ge9 provides reactive building blocks for a targeted synthesis of germanium-rich molecules. The silylation of Ge9 clusters with

We report on the synthesis of new derivatives of silylated clusters of the type [Ge9 (SiR3 )3 ]- (R = SiMe3 , Me = CH3 ; R = Ph, Ph = C6 H5 ) as well as on their reactivity towards copper and zinc compounds. The silylated cluster compounds were synth

From solutions of K[Ge9{Si(SiMe3)3}3] with 1,3-bis(2,6-diisopropylphenyl-)imidazol-2-ylidene (dipp) two new compounds were obtained. From toluene, single crystals of [K(dipp)2][Ge9{Si(SiMe3)3}3]·tol (1) (tol = toluene) were isolated and the crystal

The coordination of Ge9 Zintl clusters at (carbene)CuI moieties is explored, and the complexes [(CAAC)Cu]2[η3-Ge9{Si(TMS)3}2] (1), (CAAC)Cu[η3-Ge9{Si(TMS)3}3] (2), and (MIC)Cu[η3-Ge9{Si(TMS)3}3] (3) are compared with their known N-heterocyclic car

Unsaturated silicon clusters with only partial substitution, and thus, “naked” Si atoms are well studied species as they are proposed intermediates in gas-phase deposition processes. Although a remarkable number of stable molecular clusters has b
