A second monoclinic polymorph of N-(pyrazin-2-yl)aniline

The two aromatic rings in the title compound, C(10)H(9)N(3), are aligned at 23.4 (1)° and the bridging C-N-C angle is 128.9 (1)°. In the crystal structure, intermolecular N-H⋯N hydrogen bonds result in a chain motif, the repeat distance of which is half the b axial length of 8.8851 (3) Å.
