Abstract
The title compound, C16H16N2O, a potential antiparasitic agent, crystallizes in the orthorhombic Pca21 space group with unit cell parameters a= 9.912(1) A, b= 9.035(1) A, c= 15.681(2) A. The crystalline structure is stabilized by weak C---H···O and C--H···Cg(π) interactions among neighboring molecules producing an efficient packing with 66.0% of occupied space. The C--H···O hydrogen bond keeps the molecules linked into supramolecular chains propagating along the a axis direction with a graph-set notation C(4), which are reinforced by C--H···Cg(π) interactions. Hirshfeld surface analysis of the intermolecular contacts reveal that the most important contributions for the crystal packing are from H··H (55.2%) and H··C/C··H (27.1%) interactions. Energy framework calculations suggest that the contacts formed between molecules are slightly dispersive in nature.
