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

The mol-ecular structure of the title compound, C(8)H(11)N(3)O, is nearly planar despite the chair conformation of the morpholine moiety. In the crystal, the mol-ecules form sheets parallel to the b axis, which are supported by non-classical hydrogen-bonding inter-actions 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 P2(1)/c with four mol-ecules in the unit cell.
