2-(3-Chloro-1,2-dihydro­pyrazin-2-yl­idene)malononitrile

In the crystal structure of the title compound, C(7)H(3)ClN(4), neighbouring mol­ecules are linked via pairs of N—H⋯N hydrogen bonds into inversion dimers, thereby forming an R (2) (2)(12) ring motif. With respective average deviations from planarity of 0.009 (1) and 0.006 (1) Å, the pyrazine skelet...

description In the crystal structure of the title compound, C(7)H(3)ClN(4), neighbouring mol­ecules are linked via pairs of N—H⋯N hydrogen bonds into inversion dimers, thereby forming an R (2) (2)(12) ring motif. With respective average deviations from planarity of 0.009 (1) and 0.006 (1) Å, the pyrazine skeleton and the malononitrile fragment are oriented at an angle of 6.0 (1)° with respect to each other. The mean planes of the pyrazine ring lie either parallel or are inclined at an angle of 68.5 (1)° in the crystal structure.
