Three-component condensation of benzylideneacetone, ethyl acetoacetate, and malononitrile in the 1:1:1 molar ratio, respectively, in the presence of equimolar quantities of piperidine and glacial acetic acid is studied. The crystal structure of the reaction product (ethyl-2-dicyanomethylene-4-methyl-6-phenyl-3-cyclohexene-1-carboxylate) determined from XRD data by the method of atom-atom potentials contains energy traps in the form of double planar and double two-sided catchers. The energy traps lead to molecular agglomerates occurring in the crystal in the form of slightly deformed translationally identical hexagonal networks.

2-二氰基亚甲基-4-甲基-6-苯基-3-环己烯-1-羧酸乙酯的合成及其分子团聚物的晶体结构

在等摩尔量的哌啶和冰醋酸存在下，分别研究了亚苄基丙酮，乙酰乙酸乙酯和丙二腈的三组分缩合反应，摩尔比为1：1：1。通过XRD数据通过原子原子势方法确定的反应产物（乙基-2-二氰基亚甲基-4-甲基-6-苯基-3-环己烯-1-甲酸乙酯）的晶体结构包含双能形式的能阱平面和双面双面捕手。能量陷阱导致分子团聚体以略微变形的平移相同的六边形网络的形式出现在晶体中。
