Ligands with enamine structures can be surprisingly well stabilized in pentacoordinate silicon complexes. These novel coordination complexes contain a central Si atom in a trigonal‐bipyramidal coordination environment, surrounded by a threefold‐deprotonated salen ligand (2×N, 2×O, see structure). The complexes are starting materials for the synthesis of novel compounds containing hexacoordinate Si atoms by acid‐addition reactions.
