This consists of Phosphorus as the central atom. Phosphorus pentafluoride has 5 regions of electron density around the central phosphorus atom (5 bonds, no lone pairs). This is an oily and sleek fluid. C&L Inventory . Hexafluorophosphoric acid (HPF6) is derived from phosphorus pentafluoride and hydrogen fluoride. The shape of this compound is that of a triangular pyramid. The phosphorus atom will be the molecule's central atom. We assume you are converting between moles Phosphorus Pentafluoride and gram. The apparent equivalency arises from the low barrier for pseudorotation via the Berry mechanism, by which the axial and equatorial fluorine atoms rapidly exchange positions. (If there is more than one angle, pick the smallest.) Two of the fluorine atoms, designated as axial, are aligned with the phosphorus atom, with P-F bond distances of 1.58 Å.The remaining three fluorine atoms, designated as equatorial, are arranged in an equilateral triangle with P-F bond distances of 1.53 Å. Silylarsines have a similar chemistry to that of the silyl phosphines. document.write("   ") document.write("   ") Phosphorus pentafluoride, P F 5, is a phosphorus halide.
