Abstract:

运用密度泛函理论(DFT)分别对高氯酸·四氨·双(5-硝基四唑)合钴(Ⅲ)(BNCP)分子和晶体进行了理论计算。首先选取4种常见密度泛函方法对BNCP气相分子进行优化,结果表明TPSS(Tao,Perdew,Staroverov,Scuseria)方法最适合此体系。随后运用MaterialsStudio中DMOL3模块中PW91方法对BNCP晶体进行周期性计算。并在优化后的结构基础上对气相分子的电子结构以及晶体的态密度、晶格能以及热力学参数进行研究。结果表明,中心金属离子和配体之间的连接为共价性;且高氯酸根离子对前沿能带贡献最大,是主要活性部位;同时给出了晶体热力学参数和温度之间的关系式并计算了晶体的晶格能。
