Pentacoordination of Silicon by Five Different Ligand Atoms: Neutral Silicon(IV) Complexes with SiClSONC and SiISONC Skeletons

Abstract

Take five: Pentacoordinate silicon with five different ligand atoms (SiClSONC and SiISONC skeletons) has been realized with the synthesis of the neutral silicon(IV) compound 1 and its iodo analogue, both of which exist in the solid state and in solution. The chloro ligand of 1 can be easily replaced to give further pentacoordinate silicon compounds.
