Reduction of the neutral carbene tetrachlorosilane adduct (cAAC)SiCl4 (cAAC=cyclic alkyl(amino) carbene :C(CMe2)2(CH2)N(2,6‐iPr2C6H3) with potassium graphite produces stable (cAAC)3Si3, a carbene‐stabilized triatomic silicon(0) molecule. The Si−Si bond lengths in (cAAC)3Si3 are 2.399(8), 2.369(8) and 2.398(8) Å, which are in the range of Si−Si single bonds. Each trigonal pyramidal silicon atom of...
Unzertrennliches Zinkpärchen: Die Reaktion von homoleptischen {GaCp*}‐Verbindungen [M(GaCp*)4] (M=Pd, Pt; Cp*=Pentamethylcyclopentadienyl) mit [Zn2Cp*2] führt zur Bildung von [M(GaCp*)2(ZnCp*)2(ZnZnCp*)2] (siehe Bild; grau C, gelb Ga, grün Zn, blau Pd) und [M(ZnCp*)4(ZnZnCp*)4]. Beide Moleküle enthalten den neuartigen Liganden {ZnZnCp*} mit einer intakten Zn‐Zn‐Bindung.
