Crystal structure of (5-methylimidazo[1,2-a]pyridin-2-yl)methanol

Abstract

In the title compound, C9H10N2O, the imidazo[1,2-a]pyridine moiety is approximately planar (r.m.s. deviation = 0.024 Å). The methanol group is nearly perpendicular to its mean plane as indicated by the C—C—C—O and N—C—C—O torsion angles of 80.04 (16) and −96.30 (17)°, respectively. In the crystal, molecules are linked by O—H...N hydrogen bonds, forming inversion dimers with an R22(10) ring motif. The dimers are liked via C—H...O hydrogen bonds, enclosing R22(10) ring motifs and forming ribbons along [201]. The ribbons are linked via a number of π–π interactions [centroid–centroid distances vary from 3.4819 (8) to 3.7212 (8) Å], forming a three-dimensional structure.
