Crystal structure and magnetic properties of LaCa(0.143 (4))O(0.857 (4))F(0.143 (4))Bi(0.857 (4))S(2)

The synthesis, structure, and magnetic properties of lithium dibarium calcium oxide fluoride di­sulfide are reported. LaCa(0.143 (4))O(0.857 (4))F(0.143 (4))Bi(0.857 (4))S(2) crystallizes in the tetra­gonal space group P4/nmm. The structure exhibits disorder of the Ca(2+) and Bi(3+) cations, and the...

Sumario:The synthesis, structure, and magnetic properties of lithium dibarium calcium oxide fluoride di­sulfide are reported. LaCa(0.143 (4))O(0.857 (4))F(0.143 (4))Bi(0.857 (4))S(2) crystallizes in the tetra­gonal 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)(2)La(2)] layers and double [(Bi,Ca)S(2)] layers. Magnetic property measurements indicate a very small magnetization at 300 K and the existence of weak ferromagnetism at 2 K.
