Samarium pentaphosphide is a binary inorganic compound of samarium metal and phosphorus with the chemical formula SmP5.[2][3]
Preparation
Samarium pentaphosphide can be prepared by heating stoichiometric amounts of samarium and phosphorus at 700 °C:
- 4 Sm + 5 P4 → 4 SmP5
Properties
Samarium pentaphosphide forms crystals of monoclinic crystal system, spatial group P121/m1 or P21.[4][5] It decomposes at 700 °C.
