Crystal structure and Hirshfeld surface analysis of (Z)-2-phenyl-4-((4,6,8-trimethylazulen-1-yl)methylene)oxazol-5(4H)-one

Abstract

The molecular structure of (Z)-2-phenyl-4-((4,6,8-trimethylazulen-1-yl)methylene)oxazol-5(4H)-one (1) was determined single-crystal X-ray diffraction. The crystal presents a monoclinic crystal system, space group P21/n, a = 7.0706(3) Å, b = 18.7978(7) Å, c = 13.7059(7) Å, β = 103.013(5) °, V = 1774.89(14) Å3. In the crystals of 1, are present strong π-π stacking interactions, with an average distance of 3.54 Å between centroids.
