Abstract

In the title compound, C25H22Cl2N2O4·CH3OH, the macrocyclic molecule adopts a slightly distorted C2-symmetric conformation. The macrocyclic molecules are linked via N—H...O hydrogen bonds between the amide groups into chains extending along the [010] direction. The methanol molecules bridge these chains via N—H...O and O—H...O hydrogen bonds with the formation of a two-dimensional polymeric structure parallel to (001). The methanol molecule is disordered over two positions with the occupancy ratio of 9:1. The disorder of the solvent molecule is caused by weak intermolecular C—H...Cl hydrogen bonding.
