Abstract

In the title compound, C(25)H(22)Cl(2)N(2)O(4)·CH(3)OH, the macrocyclic mol-ecule adopts a slightly distorted C(2)-symmetric conformation. The macrocyclic mol-ecules are linked via N-H⋯O hydrogen bonds between the amide groups into chains extending along the [010] direction. The methanol mol-ecules 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 mol-ecule 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.
