Redetermination of the twinned structure of triacetone amine monohydrate.
The structure of triacetone amine monohydrate (systematic name: 2,2,6,6-tetramethylpiperidin-4-one monohydrate), C(9)H(17)NO.H(2)O, has been redetermined at 180K. The compound crystallizes in space group P2(1)/c with a monoclinic angle of 90.084(3) degree. All crystals examined exhibited twinning and appeared orthorhombic, with a unit-cell volume half that of the true volume.
