The formability of complex flourides has been studied by chemical bond parameter-patternrecognition method. In a multi-dimensional space spanned by ionic radius, ionicpolarizability, electronegativity and ionic charge of the metal elements, the binary complexflouride-forming systems and binary flouride systems without complex flouride formation distributein different regions with a clear-cut boundary. The mathematical models obtained areuseful for new complex flouride predicton.
