Description
Summary:The title compound, i.e., <i>(Z)</i>-4-(azulen-1-ylmethylene)-2-phenyloxazol-5(4<i>H</i>)-one (<b>3</b>), has previously been synthesized in a good yield (56%) using the Erlenmeyer–Plöchl procedure. The crystal structure of <b>3</b> is described herein along with the results of a Hirshfeld surface analysis. Crystals of compound <b>3</b> were obtained through the slow evaporation of a mixture of petroleum ether/dichloromethane = 1:1 (vol.) at room temperature. This compound has a monoclinic system: a P2<sub>1</sub>/n space group at room temperature. Its crystal packing is driven by π-π interactions between neighboring molecules in the range of 3.60–3.71 Å and by hydrogen bonds (D-H···A = 2.58 Å).
