Crystal structure and Hirshfeld surface analysis of N-(tert-but-yl)-2-(phenyl-ethyn-yl)imidazo[1,2-a]pyridin-3-amine.


ABSTRACT: The bicyclic imidazo[1,2-a]pyridine core of the title compound, C19H19N3, is relatively planar with an r.m.s. deviation of 0.040?Å. The phenyl ring is inclined to the mean plane of the imidazo[1,2-a]pyridine unit by 18.2?(1)°. In the crystal, mol-ecules are linked by N-H?H hydrogen bonds, forming chains along the c-axis direction. The chains are linked by C-H?? inter-actions, forming slabs parallel to the ac plane. The Hirshfeld surface analysis and fingerprint plots reveal that the crystal structure is dominated by H?H (54%) and C?H/H?C (35.6%) contacts. The crystal studied was refined as an inversion twin.
