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

运用化学键参数-模式识别方法,对金属复氟化物的形成规律作了分析。研究表明:在以金属元素的价态,离子半径,电负性和极化率构成的高维空间中,能形成复氟化物的氟化物二元系分布在该空间的一个特定区域。据此可预测一系列可能存在的复氟化物。
