Abstract
The silanide [Si4{N(SiMe3)Dipp}3]− (1) transforms into the anionic siliconoid cluster [Si7{N(SiMe3)Dipp}3]− (2) with four unsubstituted silicon atoms as a contact ion pair with [K([18]crown‐6)] in C6D6 at room temperature within five weeks. Anion 2 was investigated by natural population analysis and visualization of intrinsic atomic orbitals. Magnetically induced current‐density calculations of 2 revealed two distinct strong diatropic vortices that sum up in one direction and create a strongly shielded apical silicon atom in 2.
