摘要
为了研究晶格能与感度之间的关系,采用微热量热计测定了[Mn(CHZ)3](NO3)2和[Mn(CHZ)3](ClO4)2在去离子水中的溶解焓,计算出它们的标准摩尔溶解焓分别为91.13kJ.mol-1和87.09kJ.mol-1,根据卡普廷斯基经验公式计算了它们的晶格能分别为1737.36kJ.mol-1和1485.36kJ.mol-1,得出配阳离子半径[Mn(CHZ)3]2+为2.12;讨论了晶格能与机械感度之间的关系:配合物的晶格能越大,感度越小,[Mn(CHZ)3](NO3)2比[Mn(CHZ)3](ClO4)2钝感。
In order to study the relationship between the structures and sensitivities of energetic coordination compounds,the enthalpies of solution of [ Mn （CHZ） 3 ] （ NO3 ） 2 and [ Mn （ CHZ ） 3 ] （ CIO4 ） 2 in deionized water were measured by a Setaram C80 Ⅱ microcalorimeter at 298.15 K. The standard molar enthalpies of solution were obtained to be 91.13 kJ · mol^ -1 for [ Mn（CHZ）3 ] （ NO3 ）2 and 87.09 kJ · mol^ -1 for [ Mn （ CHZ ） 3 ] （ CIO4 ） 2- Their lattice energy were calculated farther as [ Mn （ CHZ ） 3 ] （ NO3 ） 2 being 1737.36 kJ · mol^ -1 and [ Mn（CHZ） 3 ] （CIO4）2 being 1485.36 kJ · mol^ -1 through Kapustinskii formula, and the thermochemistry radius of [ Mn（CHZ） 3 ] ^2 ＋ was obtained to be 2.12A. The relationship between lattice energy and impact sensitivity or friction sensitivity was discussed. The more the lattice energy is, the lower the sensitivity is. [ Mn（CHZ） 3 ] （NO3）2 is more insensitive than [ Mn（CHZ）3 ] （CIO4）2.
