Abstract
The chair-shaped molecules in the crystal consist in two pairs of enantiomers with two conformations (ratio 1:3), differing only in the position of two ring carbon atoms.
The chair-shaped molecules in the title crystal, C11H16N2O2Se, consist of two pairs of enantiomers with two conformations (ratio 1:3), differing only in the position of two ring carbon atoms. Two molecules are connected via carboxylic acid hydrogen bridges.
