Abstract
In the first reported crystal structure involving the potential ligand N,N′,N′′-tris(pyridin-2-yl)benzene-1,3,5-tricarboxamide, C24H18N6O3, intermolecular N—H...O hydrogen bonds link the molecules via their amide groups into slanted ladder-like chains, in which the uprights of the ladder are formed by the hydrogen-bonding interactions and the benzene ring cores of the molecules act as the rungs of the ladder. Only two of the three amide groups in the molecule are involved in hydrogen bonding and this influences the degree of out-of-plane twisting at each amide group, with the twist being more significant for those amide groups participating in hydrogen bonds.
