Crystal structure of mandipropamid

Abstract

In the title compound, C23H22ClNO4 (systematic name: (RS)-2-(4-chlorophenyl)-N-{2-[3-methoxy-4-(prop-2-yn-1-yloxy)phenyl]ethyl}-2-(prop-2-ynyloxy)acetamide), an amide fungicide, the dihedral angle between the chlorobenzene and benzene rings is 65.36 (6)°. In the crystal, N—H...O hydrogen bonds lead to zigzag supramolecular chains along the c axis (glide symmetry). These are connected into layers by C—H...O and C—H...π interactions; the layers stack along the a axis with no specific intermolecular interactions between them.
