5272(11) Å, b = 17.774(2) Å, c = 10.2732(14) Å, β = 111.005(2)° and Z = 4. The number of weak but significant C–H···O, C–H···N, C–F···π and π–π interactions take part, in the stability of the crystal packing and also the quantitative contributions of these interactions towards the crystal packing are investigated by Hirshfeld surface analysis. A static disorders have been observed in isopropyl substituent
嘧啶衍生物是众所周知的含氮杂环化合物,在医药应用中起着重要作用。合成的化合物 2-氯-4-(4-氟-苯基)-6-异丙基-嘧啶-5-羧酸甲酯已通过单晶 X 射线衍射研究得到证实。标题化合物在单斜空间群 P21/c 中结晶,a = 8.5272(11) Å,b = 17.774(2) Å,c = 10.2732(14) Å,β = 111.005(2)°,Z = 4。微弱但显着的 C–H…O、C–H…N、C–F…π 和 π–π 相互作用参与了晶体堆积的稳定性以及这些相互作用对通过 Hirshfeld 表面分析研究晶体堆积。由于各向异性的热运动,在原子 C20 和 C21 的异丙基取代基中观察到静态紊乱。分别使用没有极化函数的RHF/6-311G和B3LYP/6-311G基组对标题分子进行了从头算和密度泛函理论(DFT)计算,预测了可以很好地再现结构参数的优化几何形状。Mullikan 电荷分布
