Abstract The crystal structure of the title compound has been determined. The molecule is non-planar, the dihedral angle between the phenyl rings is equal to 84.2(10)°. In crystal, weak C-H…O hydrogen bonds combine molecules in infinite chains. Crystal packing does not reveal features typical for enantiotropic mesomorphous compounds. This is in accordance with the DSC data showing that the compound is subjected to the Cr – Iso – N – Cr phase transitions on heating followed by cooling the melt.

介晶 4-正丁氧基苯基-4'-甲基丙烯酰氧基苯甲酸酯的 X 射线结构和 DSC，CH2=C(CH3)-COO-C6H4-COO-C6H4-O-C4H9

摘要 标题化合物的晶体结构已确定。分子是非平面的，苯环之间的二面角等于84.2(10)°。在晶体中，弱的 CH…O 氢键将分子结合成无限链。晶体堆积没有揭示对映性介晶化合物的典型特征。这与 DSC 数据一致，表明该化合物在加热后经历 Cr - Iso - N - Cr 相变，然后冷却熔体。
