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.
