Crystal structure and Hirshfeld surface analysis of (Z)-4-(4-hydroxybenzylidene)-3-methylisoxazol-5(4H)-one

Abstract

In the crystal of the title compound, mol­ecules stack head-to-tail in columns along the b-axis direction, and are linked by offset π–π inter­actions [inter­centroid distances of 3.676 (1) and 3.723 (1) Å].
