aluminum chloride and cobalt(ii) chloride vapors were studied by low-temperature (80—200 K) IR spectroscopy. In addition to 2 : 1 complexes, previously unknown equimolar associates were found and their IR spectra were investigated. Quantum-mechanical calculations were carried out including electron correlation with the use of the B3LYP and PBE density functionals. The geometric structures were optimized
通过低温 (80-200 K) 红外光谱研究氯化铝和氯化钴 (ii) 蒸气的共缩合产物。除了 2 : 1 配合物外,还发现了以前未知的等摩尔缔合物,并对它们的红外光谱进行了研究。进行了量子力学计算,包括使用 B3LYP 和 PBE 密度泛函的电子相关性。优化了几何结构,计算了氯化铝、氯化钴及其不同成分配合物的分子谐振频率。在分子运动受限的条件下,(AlCl3)2·CoCl2 配合物可以稳定在四面体或扭曲八面体环境中含有 Co 原子的结构中。确定了它们的热稳定性极限。
