为了求得RO_4~(n-)(R=Si,P,S,Se,Te,Cl)离子中R—O键强度(A_(R-O)~λ)参数与H_nRO_4,RO_4~(n-)或其盐性质之间的定量关系,采用线性回归计算,得到(A_(R-O)~λ)对RO_4~(n-)中R—O之间重叠积分,R--O键长,RO_4~(n-)的热化学半径,水合热,钾盐热稳定性,H_nRO_4一级电离常数(pKa_1)等性质之间的六个线性方程,其相关系数绝对值范围为0.9662≤|R|≤0.9988。这表明(A_(R-O)~λ)与RO_4~(n-)离子性质之间存在着良好的线性关系,计算结果与实验值相一致。
In order to obtain the relationship between the R-O bond intensity (A ROI ~ λ) in RO_4 ~ (n -) (R = Si, P, S, Se, Te, Cl) ions and H_nRO_4, RO_4 ~ (n-) The quantitative relationship between the R-O and R-O in RO_4 ~ (n-) was obtained by the linear regression. The relationship between the R_O bond length and RO_4 ~ (n) -) thermodynamic radius, hydration heat, potassium thermal stability, H_nRO_4 first order ionization constant (pKa_1) and other properties of the six linear equations, the absolute value of the correlation coefficient range of 0.9662 ≤ | R | ≤ 0.9988. This shows that there is a good linear relationship between the (A_ (R-O) ~ λ) and the properties of RO_4 ~ (n-) ions. The calculated results are consistent with the experimental values.
