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 inter-molecular distances between the centroids of the 2,3-dihydro-pyrazine and benzene rings [3.6490 (5) Å] indicate the existence of π⋯π inter-actions. In the crystal packing, the mol-ecules are linked via two pairs of inter-molecular C-H⋯N inter-actions, forming R(2...
متن کامل2-(4-Iodophenyl)-1,2,3,4-tetrahydroisoquinoline-1-carbonitrile
In the title compound, C(16)H(13)IN(2), the benzene ring of the tetra-hydro-isoquinoline moiety makes a dihedral angle of 45.02 (9)° with the benzene ring of the 4-iodo-phenyl fragment. The N atom and the adjacent unsubstituted C atom of the tetra-hydro-isoquinoline unit are displaced by 0.294 (2) and 0.441 (3) Å, respectively, from the plane through the remaining eight C atoms. In the crystal,...
متن کاملOxalic acid–pyridine-4-carbonitrile (1/2)
In the title compound, 2C(6)H(4)N(2)·C(2)H(2)O(4), the oxalic acid mol-ecule lies about an inversion center. The pyridine ring of the pyridine-4-carbonitrile mol-ecule is almost planar, the largest deviation from the least-squares plane being 0.006 (1) Å; the nitrile N atom deviates from this plane by 0.114 (1) Å. In the crystal, the oxalic acid mol-ecules and the pyridine-4-carbonitrile mol-ec...
متن کامل2-(4-Bromophenyl)quinoxaline
In the title compound, C(14)H(9)BrN(2), the benzene and quinoxaline rings are almost coplanar [r.m.s. deviation = 0.0285 (3) Å and dihedral angle = 2.1 (2)°].
متن کامل2-(4-Chloroanilino)quinoxaline
There are two mol-ecules in the asymmetric unit of the title compound, C(14)H(10)ClN(3), with dihedral angles of 5.11 (10) and 13.61 (10)° between the aromatic ring systems. In the crystal structure, mol-ecules are linked by N-H⋯N hydrogen bonds, resulting in chains propagating in [010].
