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[edit]

Thorium heptaphosphide can be synthesized from the elements with addition of iodine at 830 K.[3][4]

Properties[edit]

Thorium heptaphosphide forms black rod-shaped crystals of orthorhombic crystal system.[1][4] It decomposes to Th2P11 at 650 K in vacuo.[3]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
