Multilateral Solid-State Metathesis Reactions for the Preparation of Materials with Heteroanions: The [Si(CN2)4]~(4-) Ion

摘要

The search for nonoxidic inorganic compounds has led beyond simple metal borides, carbides, nitrides, and silicides to the development of interesting materials in whose structures several nonmetallic elements are combined. For example, in the structures of the well-known compounds Ti(C,N) and Mo2BN, the anions are combined, but are present without bonds between the heteroatoms. An extension to this type of compound comprises metal compounds with element combinations of boron, carbon, nitrogen, and silicon. These elements are bridged to form complex units or ions through heteropolar, covalent bonds.
