Crystal structure and Hirshfeld surface analysis of 3,3′-[ethane-1,2-diylbis(­oxy)]bis­(5,5-di­methyl­cyclo­hex-2-en-1-one) including an unknown solvate

Abstract

In the crystal, the mol­ecules are connected into dimers by C—H⋯O hydrogen bonds with

(8) ring motifs, forming zigzag ribbons along the b-axis direction.

The title mol­ecule, C₁₈H₂₆O₄, consists of two symmetrical halves related by the inversion centre at the mid-point of the central –C—C– bond. The hexene ring adopts an envelope conformation. In the crystal, the mol­ecules are connected into dimers by C—H⋯O hydrogen bonds with R ² ₂(8) ring motifs, forming zigzag ribbons along the b-axis direction. According to a Hirshfeld surface analysis, H⋯H (68.2%) and O⋯H/H⋯O (25.9%) inter­actions are the most significant contributors to the crystal packing. The contribution of some disordered solvent to the scattering was removed using the SQUEEZE routine [Spek (2015#). Acta Cryst. C71, 9–18] in PLATON. The solvent contribution was not included in the reported mol­ecular weight and density.
