    Due to the large size of the La 3+ ion, La 2 O 3 adopts a hexagonal 7-coordinate structure that changes to the 6-coordinate structure of scandium oxide (Sc 2 O 3) and yttrium oxide (Y 2 O 3) at high temperature. When it reacts with water, lanthanum hydroxide is formed: [37] a lot of heat is evolved in the reaction and a hissing sound is heard.

    2 La + 3 S → La 2 S 3. It can also be prepared from the effect of hydrogen sulfide on lanthanum: 2 La + 3H 2 S → La 2 S 3 + 3 H 2. The effect of hydrogen sulfide on lanthanum oxide in the presence of reducing agents also produces lanthanum(III) sulfide: La 2 O 3 + 3 H 2 S + 3 C → La 2 S 3 + 3 CO 2 + 3 H 2
