The preparation, properties, and crystal structures of some scandium sulfides in the range Sc2S3-ScS

Scandium sesquisulfide, Sc2S3, was prepared by the high-temperature reaction of hydrogen sulfide with scandium sesquioxide. Due to the problem of stoichiometry associated with the high melting point, 1775°, stoichiometric crystals of Sc2S3 were prepared by chemical transport with I2 at 950°. A nonstoichiometric material containing an excess of scandium compared with Sc2S3 was prepared by heating Sc2S3 under vacuum at 1650°. Crystals of ScS were prepared by the reaction of scandium metal with sulfur. The crystal structure of Sc2S3 is closely related to that of NaCl, but the unit cell is twelve times as large due to a complex ordering arrangement of the cation voids. Each octahedron surrounding sulfur has two vertices empty, and the bond angles are all very close to 90°. The nonstoichiometric material has a much simpler structure which is also closely related to that of NaCl, with Sc1.37S2 per rhombohedral unit cell. This structure, in which one cation site is filled and the other is only partially occupied, could exist over the whole range between Sc2S3 and ScS, which was found to have the NaCl structure. Stoichiometric Sc2S3 is a semiconductor with a band gap of about 2 e.V., but the materials between Sc2S3 and ScS are good electrical conductors. Electrical conduction in the latter materials appears to involve a 3d band.

On the reactivity of lanthanide iodides LnIx (x < 3) formed in the reactions of lanthanide metals with iodine

The reduced lanthanide iodides of the composition LnIx (Ln = Sc, Y, La, Ce, Pr, Gd, Ho, and Er; x 3) were obtained by the reaction of an excess of the appropriate metal with iodine at high temperatures. The diamagnetism of the Sc, Y, and La d
