Thorium heptaphosphide is a binary inorganic compound of thorium metal and phosphorus with the chemical formula ThP7.[2] This is the most phosphorus-rich binary compound of a tetravalent thorium.[3]
Synthesis
Thorium heptaphosphide can be synthesized from the elements with addition of iodine at 830 K.[3][4]
Properties
Thorium heptaphosphide forms black rod-shaped crystals of orthorhombic crystal system.[1][4] It decomposes to Th2P11 at 650 K in vacuo.[3]
