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.

Recent advances in "hybrid-improper" ferroelectricity in Dion-Jacobson (DJ)-type layered perovskites have caused renewed interest in the search for new ferroelectrics. Here, we present an approach for the tailored synthesis of a new homologous series of DJ-type layered perovskites Cs(BiSr)(TiNb)O. Starting from CsBiTiNbO ( = 3), higher-order homologous phases with = 4 and 5 were successfully synthesized by repeated solid-state calcination with SrTiO.

Flexible control of the composition and morphology of nanocrystals (NCs) over a wide range is an essential technology for the creation of functional nanomaterials. Cation exchange (CE) is a facile method by which to finely tune the compositions of ionic NCs, providing an opportunity to obtain complex nanostructures that are difficult to form using conventional chemical synthesis procedures. However, due to their robust anion frameworks, CE cannot typically be used to modify the original morphology of the host NCs.
