Abstract
A cyclic hexamer of 4-(methylamino)benzoic acid was crystallized from dichloromethane-ethyl acetate to give colorless prisms, which belonged to space group P1 with a = 12.441(1)A, b = 16.003(1)A, c = 11.7479(9)A α = 94.421(7)°, β = 117.911(5)°, γ = 100.205(7)°, V = 1999.5(3)A3, and Z = 2. The compound adopted a folded conformation with all six N-methylamides having a cis (E) conformation; four intermolecular CH/n contacts were observed in the crystal.
