Crystal structure of dimethyl N,N′-[(ethyne-1,2-diyl)bis(1,4-phenylenecarbonyl)]bis(l-alaninate)

Crystal structure of dimethyl N,N′-[(ethyne-1,2-diyl)bis(1,4-phenylenecarbonyl)]bis(l-alaninate)

The diphenylethyne unit of the title molecule, C24H24N2O6, deviates slightly from planarity. The l-alanine moieties adopt distorted helical conformations of opposite winding direction. Infinite ribbons of N—H...O=C-connected molecules represent the basic supramolecular entities of the crystal struct...
