Two non-bonding VSCCs found in a silylone: An experimental and theoretical charge-density study confirms the interpretation of (cAAC)2Si as a silylone to be valid. The two separated VSCCs present in the non-bonding region of the central silicon are indicative for two lone pairs. The nitrogen–carbene-carbon bond seems to have a significant double bond character, indicating a singlet state for the carbene carbon atom.
