2-(2-Naphth­yl)-1,3-dioxane

The title compound, C(14)H(14)O(2), crystallizes in the chiral monoclinic space group P2(1). This acetal is composed of a planar naphthalene ring with a 1,3-dioxane ring substituent, which has a chair conformation. In the crystal structure, symmetry-related mol­ecules are connected via a weak C—H⋯O inter­action to form a helical chain propagating in [010]. While there are no π–π stacking inter­actions present, there are weak C—H⋯π inter­actions involving the naphthalene aromatic rings, which link the helical chains to form a two-dimensional network in the (011) plane.
