title: 6-Hy-droxy-2,5,7,8-tetra-methyl-3,4-dihydro-2H-1-benzopyran-2-carbonitrile, from synchrotron data.
abstract: The crystal structure of the title compound, C(14)H(17)NO(2), solved and refined against synchrotron diffraction data, contains one formula unit in an asymmetric unit. In the crystal, mol-ecules form right-handed helices located at the 2(1) screw axis parallel to the a-axis direction, generated by O-H⋯N hydrogen bonding between the hy-droxy group and carbonitrile group of an adjacent mol-ecule.
