The synthesized compound was characterized by P, C, and H NMR spectroscopy and MALDI-TOF mass spectroscopy. According to DSC data, the compound was initially crystalline, but the crystal structure was defective. The crystals suitable for X-ray diffraction study were prepared by slow precipitation of the compound from a solution by a vapor of another solvent. A study of the single crystal obtained in this way demonstrated that the phosphazene ring has a flattened chair conformation. It was found that the sphere circumscribed around the compound molecule has a diameter of 2.382 nm.
通过磷、碳和氢核磁共振光谱以及基质辅助激光解吸电离飞行时间质谱对合成的化合物进行了表征。根据差示扫描量热法数据，该化合物最初是结晶的，但晶体结构存在缺陷。通过另一种溶剂的蒸汽使化合物从溶液中缓慢沉淀来制备适合X射线衍射研究的晶体。对以这种方式获得的单晶的研究表明，磷腈环具有扁平的椅式构象。发现围绕化合物分子外接的球体直径为2.382纳米。
