Especially in G protein systems AlF4−has been claimed as an activating species serving as a tetrahedral phosphate analog. However, in aqueous solutions (H20)2AlF4−is hexacoordinate with two bound water molecules. In neutral solutions five different mixed OH−and F−complexes of A13+comprise the main species under usual experimental conditions. Comparison of the mole fraction distribution curves with limited results on the activity as a function of ambient F−concentrations suggests an activating complex composed of A13+with three F−and uncertain geometry. Even fewer activity data suggest a tetrahedral Be2+complex with three F−.
