Quinoxaline-2-carbonitrile

In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter­molecular distances between the centroids of the 2,3-dihydro­pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter­actions. In the crystal pac...

description In the title compound, C(9)H(5)N(3), the quinoxaline ring is essentially planar, with a maximum deviation of 0.012 (1) Å. Short inter­molecular distances between the centroids of the 2,3-dihydro­pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter­actions. In the crystal packing, the mol­ecules are linked via two pairs of inter­molecular C—H⋯N inter­actions, forming R (2) (2) (8) and R (2) (2) (10) ring motifs; these mol­ecules are further linked into a two-dimensional network parallel to (1 0 2) via another C–H⋯N inter­action.
