different assemblies and synthons have been studied using Hirshfeld surface analysis and by computing their interaction energies and different contributions (electrostatic, polarization, dispersion and repulsion). Furthermore, only one isomer forms directional halogen bonding interactions (C–Cl⋯O) that have been analyzed using MEP surface calculations and characterized using a combination of QTAIM and
这项工作报告了三种二氯苯基取代的 3-羟基-chromen-4-one 衍生物的合成和 X 射线表征,即2-(2,4-dichlorophenyl)-3-hydroxy-4 H -chromen-4-one ( 1 ), 2-(2,3-二氯苯基)-3-羟基-4 H -chromen-4-one ( 2 ), 和 2-(2,6-二氯苯基)-3-羟基-4 H -chromen-4 -一 ( 3)。由于 Cl 取代基对苯基环和色酮环之间的二面角影响很大,这三种异构体的固态结构大不相同。已经使用 Hirshfeld 表面分析并通过计算它们的相互作用能和不同的贡献(静电、极化、色散和排斥)来研究不同的组件和合成子。此外,只有一种异构体形成定向卤素键相互作用(C-Cl⋯O),已使用 MEP 表面计算进行分析,并使用 QTAIM 和 NCIplot 指数计算方法的组合进行表征。还分析了根据取代形成卤素键
