Main group analogues of cyclobutane-1,3-diyls are fascinating due to their unique reactivity and electronic properties. So far only heteronuclear examples have been isolated. Here we report the isolation and c

Small‐ to medium‐sized clusters occur in various areas of chemistry, for example, as active species of heterogeneous catalysis or as transient intermediates during chemical vapor deposition. The manipulation of stable representatives is mostly li

The recent progress in the synthesis of partially substituted neutral silicon clusters (siliconoids) revealed unique structures and electronic anisotropies that are reminiscent of bulk and nano surfaces of silicon. Here, we report the selective 2-lit

Unsaturated charge‐neutral silicon clusters (siliconoids) are important as gas‐phase intermediates between molecules and the elemental bulk. With stable zirconocene‐ and hafnocene‐substituted derivatives, we here report the first examples con

The highly reactive silicon congeners of cyclopropene, cyclotrisilenes (c-Si3 R4 ), typically undergo either π-addition to the Si=Si double bond or σ-insertion into the Si-Si single bond. In contrast, treatment of c-Si3 Tip4 (Tip=2,4,6-i Pr3 C6 H2

The characteristic features of bulk silicon surfaces are echoed in the related partially substituted—and thus unsaturated—neutral silicon clusters (siliconoids). The incorporation of siliconoids into more‐extended frameworks is promising owing

A new type of Si(II): A novel silylene stabilized by a Cp* and an imidazolin-2-iminato ligand has been prepared using two different methods. The X-ray crystallographic structure shows that the silicon(II) center is coordinated to an η(2)-Cp* ligand

Ab-initio calculations have been performed for the half-sandwich cation [(Me5C5)Si]+ and its DME complex [(Me5C5)Si(DME)]+. For these cations, the ground state energies, the complexation energy, the frontier orbitals, the vertical singlet-triplet exc

Reaction of the Cp*Si+ cation with the beta-diketiminato anion [HC(CMeNAryl)(2)](-) (Aryl=2,6-iPr(2)C(6)H(3)) did not lead to the expected silicon(II) compound Cp*[HC(CMeNAryl)(2)]Si (3) but to the constitutional isomer 7 containing a silicon(IV) cen
