Potassium permanganate is the chemical compound KMnO4. In this salt, manganese is in the +7 oxidation state. The salt is also known as "permanganate of potash." The permanganate ion is a strong oxidizing agent. It dissolves in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals.[1] It has a sweet taste and is odourless.
Standard enthalpy of formation is ΔfH°solid = -813.4 kJ.mol-1 and standard molar entropy is S°solid = 171.7 J.K-1.mol-1.
Its crystal structure is orthorhombic with constants: a = 9.105, b = 5.720, c = 7.425 (.10-1 nm). Distance between Mn and O atoms in tetrahedral anions is 162.9 pm.

baraa that's potassium dichromate, other than grayman who forgot the n in Mn everyone else is right.
