Abstract
In the title chalcone derivative, C19H18O3, the cyclo-hexa-none ring adopts a distorted half-chair conformation and the dihedral angle between the aromatic rings is 52.20 (15)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into C(12) [001] chains.

Summary
Chalcone derivatives exhibit various biological activities (Tajuddeen et al, 2018) and those that crystallize in non-centrosymmetric space groups are candidates for non-linear optical materials (Shettigar et al, 2006). As part of our studies in this area, we describe the synthesis and structure of the title compound, C19H18O3, (I), (Fig. 1). The geometrical data for (I) are similar to those in related structures (Biruntha et al, 2018; Baydere et al, 2019). The dihedral angle between the C1–C6 and C12–C17 aromatic rings is 52.20 (15) and the C atoms of both methoxy groups lie close to the C12–C17 plane [deviations = 0.057 (4) for C18 and 0.148 (6) Afor C19]. Weak C2—H2Á Á ÁO3 hydrogen bonds link the molecules into C(12) zigzag chains propagating in the [001] direction with adjacent molecules related by a 21 screw axis (Table 1, Fig. 2).
