Crystal structure of 4-(pyrazin-2-yl)morpholine

Abstract

The molecular structure of the title compound, C8H11N3O, is nearly planar despite the chair conformation of the morpholine moiety. In the crystal, the molecules form sheets parallel to the b axis, which are supported by non-classical hydrogen-bonding interactions between C—H functionalities and the O atom of morpholine and the 4-N atom of pyrazine, respectively. The title compound crystallizes in the monoclinic space group P21/c with four molecules in the unit cell.
