A new one‐dimensional hydrogen‐bonded polymer with a unique meso ‐helical structure has been prepared from the spontaneous self‐assembly in the solid‐state of meta ‐substituted phenylene dioxamic acid diethyl ester monomers. The helical nature of this molecule and its self‐complementary character, through intermolecular hydrogen bonding between oxamic acid ester functions, are the two main factors responsible for the crystalline aggregation process, as confirmed by both experimental X‐ray crystallographic data and theoretical ab initio calculations.
