An Anionic Amido‐Substituted Seven‐Vertex Siliconoid Cluster

The silanide [Si(4){N(SiMe(3))Dipp}(3)](−) (1) transforms into the anionic siliconoid cluster [Si(7){N(SiMe(3))Dipp}(3)](−) (2) with four unsubstituted silicon atoms as a contact ion pair with [K([18]crown‐6)] in C(6)D(6) at room temperature within five weeks. Anion 2 was investigated by natural pop...

Sumario:The silanide [Si(4){N(SiMe(3))Dipp}(3)](−) (1) transforms into the anionic siliconoid cluster [Si(7){N(SiMe(3))Dipp}(3)](−) (2) with four unsubstituted silicon atoms as a contact ion pair with [K([18]crown‐6)] in C(6)D(6) 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.
