摘要
借助分子外观特征及基本化学参数,定义一个新的结构参数C(C=(m+(1/5)r4)/nR0.5.使用最小二乘法,将P区元素13种单中心无机氢化物的pKa实验值与其C关联,拟合得pKa=-21.936+25.7451C(r=0.9953).在引入参数较少的情况下,获得了满意的结果.
In this paper,a new structural parameter C(C=(m+(1/5)r^4)/n_R^(0.5)) is defined by means of the character of the molecular and fundamental chemical parameters .Using least square fitting, the observed walues of 13 single central inorganic hydride are correlated with their C, the equation is pK_a=-21.936+25.745 1C (r=0.995 3).
