Abstract Two rare earth oxysulfides Ln 5V3O7S6 (Ln = La, Ce) have been synthesized and their structures determined. The two isostructural compounds crystallize in the orthorhombic space group Pmmn (no. 59). The structure features one-dimensional edge-sharing VS4O2 octahedron chains parallel to the b axis. The bonding between V and S/O is covalent, and between Ln 3+ and the rest of the matrix ionic. Magnetic susceptibility measurement revealed that V is in a mixed valence state of V3+ and V4+. Its magnetic behavior follows the Curie-Weiss law.

Paramagnetic Properties

Some paramagnetic properties are given for a number of ternary rare earth compounds isomorphous with Sr2EuFeO5. Temperature variation of magnetic susceptibility obeys the Curie-Weiss law with exeptions for europium and samarium. Magnetic moments exhibited are close to that theoretically expected for the free ion except for europium whose value is a little higher.
