Infinitely adaptive transition-metal ordering in Ln2O2MSe2-type oxychalcogenides.

Ainsworth, Chris M. and Wang, Chun-Hai and Johnston, Hannah E. and McCabe, Emma E. and Tucker, Matthew G. and Brand, Helen E. A. and Evans, John S. O. (2015) 'Infinitely adaptive transition-metal ordering in Ln2O2MSe2-type oxychalcogenides.', Inorganic chemistry., 54 (15). pp. 7230-7238.


The origin of transition-metal ordering in Ln2O2MSe2 oxychalcogenides has been revealed by investigating a range of solid solutions. Transition-metal ordering is determined by the relative sizes of [Ln2O2]2+ and [MSe2]2− layers and can be exquisitely tuned by substitution in either layer, leading to an “infinitely adaptive” structural family. The proportion of the inherently smaller corner-shared motif increases as the transition-metal size increases relative to the lanthanide oxide layers.
