Metal compounds with heteroatomic ring systems of main group elements are a domain of coordination chemistry. However, lanthanide nitrido borates Ln3 B3 N6 (Ln=La or Ce; see structure) are synthesized by the reaction of hexagonal boron nitride with LnN. The compounds contain the six-membered B3 N6 ring, which can be seen as a fragment from one layer of the hexagonal BN structure.
Keywords: Electronic structure; Lanthanides; Materials science; Nitrido borates; Solid-state structures.
