The synthesis, structure, and magnetic properties of lithium dibarium calcium oxide fluoride di-sulfide are reported. LaCa0.143â (4)O0.857â (4)F0.143â (4)Bi0.857â (4)S2 crystallizes in the tetra-gonal space group P4/nmm. The structure exhibits disorder of the Ca(2+) and Bi(3+) cations, and the O(2-) and F(-) anions. The structure is composed of a stacking of [(O,F)2La2] layers and double [(Bi,Ca)S2] layers. Magnetic property measurements indicate a very small magnetization at 300â K and the existence of weak ferromagnetism at 2â K.
