Structure of red phosphorus
WebChemical Properties of Red Phosphorus This allotrope of phosphorus exists in a polymeric chain consisting of tetrahedrally structured P 4 molecules. Breaking off one of the bonds results in a polymer-like structure, as the broken molecules proceed to bond with the neighbouring phosphorus atoms. Red phosphorus is odourless and has a deep red colour. WebDec 2, 2024 · Since the discovery of amorphous red phosphorus (a-red P) in 1847, many possible structures have been proposed.
