Study on the Thermal Motion N-Phenylphthalimide and 2-Phenylquinoxaline in Solid State
Abstract:
On the basis of the data of single crystal structure analysis, the thermal motion analysis for the crystal molecules of N-phenylphthalimide (Ⅰ) and 2-phenylquinoxaline (Ⅱ) was carried out. It is shown that in solid state the molecule of compound I behaves dynamicaly as a rigid molecule and an intramolecular vibration of the substitued pheny group with <ω~2>=53(25) deg·~2 around C(8)—C(9) should be included in the molecular thermal motion of compound Ⅱ .
