dc.description.abstractA number of Ln2O2MSe2 (Ln = La and Ce; M = Fe, Zn, Mn, and Cd) compounds, built from alternating layers of fluorite-like [Ln2O2]2+ sheets and antifluorite-like [MSe2]2– sheets, have recently been reported in the literatures. The available MSe4/2 tetrahedral sites are half-occupied, and different compositions display different ordering patterns: [MSe2]2– layers contain MSe4/2 tetrahedra that are exclusively edge-sharing (stripe-like), exclusively corner-sharing (checkerboard-like), or mixtures of both. This paper reports 60 new compositions in this family. We reveal that the transition-metal arrangement can be systematically controlled by either Ln or M doping, leading to an “infinitely adaptive” structural family. We show how this is achieved in La2O2Fe1–xZnxSe2, La2O2Zn1–xMnxSe2, La2O2Mn1–xCdxSe2, Ce2O2Fe1–xZnxSe2, Ce2O2Zn1–xMnxSe2, Ce2O2Mn1–xCdxSe2, La2–yCeyO2FeSe2, La2–yCeyO2ZnSe2, La2–yCeyO2MnSe2, and La2–yCeyO2CdSe2 solid solutions. © 2015 American Chemical Societyen_AU
