【摘要】：通过Bravais-Freidel-Donnay-Harker(BFDH法)和growth morphology(生长形态法)方法,研究了高氯酸碳酰肼锰、高氯酸碳酰肼铁、高氯酸碳酰肼钴、高氯酸碳酰肼镍和高氯酸碳酰肼镉的晶体生长形态。结果表明,这5种化合物的晶形均接近长块状,在(101)和(002)晶面的相对生长速度最小,为晶体的最重要的生长方向。根据晶体的主要生长晶面,推断出官能团中具有活性氢原子的晶形控制剂可以有效地控制晶形。此外,通过实验合成这5中配合物,并用冷场发射扫描电子显微镜观察其晶体形貌,通过对比表明growth morphology的模拟结果更接近实验所得形貌,因此该方法可以更可靠地预测高氯酸碳酰肼金属配合物的晶体形态。
[Abstract]:The crystal growth morphology of manganese carbohydrazide perchlorate, ferric carbohydrazide perchlorate, cobalt carbohydrazide perchlorate, nickel carbohydrazide perchlorate and cadmium carbohydrazide perchlorate were studied by Bravais-Freidel-Donnay-Harker(BFDH method and growth morphologymethod. The results show that the crystal shape of the five compounds is close to the long block shape, and the relative growth rate of the five compounds is the least in the crystal plane of 101and 002), which is the most important growth direction of the crystal. According to the main growth planes of the crystal, it is inferred that the crystal shape control agent with active hydrogen atom in the functional group can effectively control the crystal shape. In addition, the complexes were synthesized experimentally and the crystal morphology was observed by cold field emission scanning electron microscope. The simulation results of growth morphology are closer to the experimental morphology. Therefore, this method can be more reliable to predict the crystal morphology of metal complexes of carbohydrazide perchlorate.
