为了研究晶格能与感度之间的关系,采用微热量计测定了[M(CHZ)3](NO3)2和[M(CHZ)3](ClO4)2(M=Mn,Zn,Ni)在去离子水中的溶解焓并计算出它们的标准摩尔溶解焓,根据卡普廷斯基经验公式计算了它们的晶格能,得出配阳离子半径[M(CHZ)3]2+(M=Mn,Zn,Ni)分别为2.12,1.89和2.70;讨论了晶格能与机械感度之间的关系:相同外阴离子系列中配合物的晶格能越大,感度越小,并且高氯酸碳酰肼盐要比相应的硝酸碳酰肼盐的晶格能低,感度最高的为[Ni(CHZ)3](ClO4)2,最钝感的为[Zn(CHZ)3](NO3)2。
In order to study the relationship between the lattice energy and the sensitivity, [M (CHZ) 3] (NO3) 2 and [M (CHZ) 3] (ClO4) 2 (M = Mn, Zn and Ni) Their enthalpies of dissolution in deionized water were calculated and their standard molar enthalpies of dissolution were calculated. Their lattice energies were calculated according to the empirical formulas of the kaputinski. The results showed that the molar enthalpy of cation [M (CHZ) 3] 2+ (M = Mn, Zn and Ni) were 2.12, 1.89 and 2.70, respectively. The relationship between lattice energy and mechanical sensitivity was discussed. The larger the lattice energy and sensitivity of the complex in the same anion series were, The hydrazide salt has a lower lattice energy than the corresponding nitrocarbonic acid hydrazide salt and the highest sensitivity is [Ni (CHZ) 3] (ClO4) 2. The most sensitive is [Zn (CHZ) 3] (NO3) 2 .
