Abstract

The molecule of the title compound, C16H18O4, is non-planar and the pyran ring adopts a half-chair conformation. Inter-molecular C - H⋯O hydrogen-bond contacts link the mol-ecules in the crystal structure, forming dimers approximately parallel to (011). © International Union of Crystallography 2007.
