凡阴离子的种类、数目相同以及阳离子的电荷数相同的离子晶体化合物,都可称为同类化合物。我们以一些同类化合物M_xA_y的标准熵S_(290)~0对组分阳离子(主族或非主族)的键参数(Z及r分别为阳离子的电荷数及离子半径)作图得到了如下一些计算同类化合物的近似公式:
Where the type of anions, the same number of positive ions and the same number of ionic crystal compounds, can be called the same type of compound. We plot some of the similar compounds M_xA_y standard entropy S_ (290) ~ 0 on the component cation (main group or non-main group) key parameters (Z and r are the cationic charge number and ionic radius) Calculate approximate formula for similar compounds:
