The missing crystal structure in the series of N,N′,N′′-tris­(pyridin-2-yl)benzene-1,3,5-tricarboxamides: the 2-pyridinyl derivative


Senior, Levi; Linden, Anthony (2020). The missing crystal structure in the series of N,N′,N′′-tris­(pyridin-2-yl)benzene-1,3,5-tricarboxamides: the 2-pyridinyl derivative. Acta Crystallographica. Section E: Structure Reports Online, 76(6):776-779.

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.
