Abstract | In the title compound, C22H22N4O 2·0.25C3H6O, the disordered acetone molecule lies with partial occupancy about the 2 axis. The molecule of the malononitrile derivative is essentially planar excluding the methyl groups, with the largest deviation from the mean plane through the non-H atoms being 0.1955 (13) Å. Two rotamers with different orientations of the benzene ring are observed in the ratio of 0.919 (2):0.081 (2), and as a result the OH group is disordered over two sets of sites. In the crystal, the molecules form ribbons along (101) utilizing a strong O - H···N(cyano) hydrogen bond. Interleaving of the nearly planar ribbons is provided by the twofold disordered acetone molecule through C - H···O interactions. |
