| Color: | /There are/ several crystalline & amorphous modifications; commercial form, hexagonal White, orthogonal crystals Exists in several forms but is often referred to by its empirical formula P2O5. Three crystalline polymorphs (H, O, O'), two distinct liquids,and several amorphous or glassy solids are recognized. The best-characterized form is the H (hexagonal) or alpha modification that consists of P4O10 molecules. |
