Crystal structure of N,N′,N′′-tri­cyclo­prop­ylbenzene-1,3,5-tricarboxamide

Abstract

In the crystal structure, the mol­ecules are connected by N—H⋯O hydrogen bonds to create two-dimensional supra­molecular networks extending parallel to the crystallographic ab plane.

The title compound, C₁₈H₂₁N₃O₃, was prepared from 1,3,5-benzene­tricarbonyl trichloride and cyclo­propyl­amine. Its crystal structure was solved in the monoclinic space group P2₁/c. In the crystal, the three amide groups of the mol­ecule are inclined at angles of 26.5 (1), 36.9 (1) and 37.8 (1)° with respect to the plane of the benzene ring. The mol­ecules are linked by N—H⋯O hydrogen bonds, forming two-dimensional supra­molecular aggregates that extend parallel to the crystallographic ab plane and are further connected by C—H⋯O contacts. As a result of the supra­molecular inter­actions, a propeller-like conformation of the title mol­ecule can be observed.
