Phosphorus mononitride is an inorganic compound with the chemical formula P N. Containing only phosphorus and nitrogen, this material is classified as a binary nitride. From the Lewis structure perspective, it can be represented with a P-N triple bond with a lone pair on each atom. It is isoelectronic with N 2, CO, P 2, CS and SiO.
Phosphorus nitride refers to several chemical compounds of phosphorus and nitrogen: Phosphorus mononitride; Tetraphosphorus hexanitride; Triphosphorus pentanitride
Phosphorus monoxide is an unstable radical inorganic compound with molecular formula P O. [2] Phosphorus monoxide is notable as one of the few molecular compounds containing phosphorus that has been detected outside of Earth. Other phosphorus containing molecules found in space include PN, PC, PC 2, HCP and PH 3.
The structure of all polymorphs of triphosphorus pentanitride was determined by single crystal X-ray diffraction. α‑ P 3 N 5 and α′‑ P 3 N 5 are formed of a network structure of PN 4 tetrahedra with 2- and 3-coordinated nitrides, [ 7 ] [ 9 ] γ‑ P 3 N 5 is composed of both PN 4 and PN 5 polyhedra [ 8 ] while δ- P 3 N 5 is composed ...
Phosphorus is a chemical element with the symbol P and the atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus , but because it is highly reactive , phosphorus is never found as a free element on Earth.
The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl orthophosphate.
Protactinium forms mixed binary oxides with various metals. With alkali metals A, the crystals have a chemical formula APaO 3 and perovskite structure, or A 3 PaO 4 and distorted rock-salt structure, or A 7 PaO 6 where oxygen atoms form a hexagonal close-packed lattice. In all these materials, protactinium ions are octahedrally coordinated.
Phosphorus dioxide (PO 2) is a gaseous oxide of phosphorus. It is a free radical that plays a role in the chemiluminescence of phosphorus and phosphine. [1] It is produced when phosphates are heated to high temperatures. [2] In the ground state the molecule is bent, like nitrogen dioxide, but there is an excited state that is linear. [1]
