Orthorhombic polymorph of 4-(2,2′:6′,2′′-terpyridin-4′-yl)aniline
Abstract
Crystallographic data for the title compound, C 21 H 16 N 4 , are reported herein. The compound was recrystallized from a methanol/acetonitrile solvent system at 298 K. It crystallizes in the Pca 2 1 space group at 100 K compared to the previously reported monoclinic polymorph and displays intermolecular hydrogen bonding, through N—H...N contacts, and π–π interactions. None of the rings in the structure is coplanar – dihedral angles defined by atoms of the peripheral rings with the central pyridine range from −7.1 (3) to 29.8 (3)°.
