In Situ Single-phase Formation of LaCl(CN) Mixed-Anion Compound Via Controlled Pyrolysis of La Modified Melamine Precursor.

Nitride (N) or cyanamide (CN) based mixed-anion compounds stand as attractive materials due to their unique properties derived from the binary or multiple anions, although their synthesis remains challenging in incorporating the N or CN anions safely. This work highlights the first demonstration of in situ single phase formation of a LaCl(CN) mixed-anion compound from a stable single source precursor, melamine modified with LaCl preparable under aqueous conditions. The in situ formation of LaCl(CN) involves the chemical modification of melamine with LaCl to form a complex.
