IMPROVEMENTS IN CHEMICAL COMPOUNDS of the Invention Certain polyoxotungstate ions, having additional atoms selected from P, transition metals and group 13 metals, and which have a metal cluster structure which is not the Keggin structure, form pharmaceutical compositions with anti-viral, especially anti-HIV, activity. Examples of compounds include those with ions of formula a), ¢P2HcW12M'xOy)pwhere M' is a transition metal, x is O or an integer from 1 to 6, y is an integer from 48 to 62, c is O, 1 or 2, and p is an integer dependent upon the oxidation state of the transition metal M'.
