5-Amino-3-ethoxy-1,8,8-trimethyl-2-azabicyclo[2.2.2]octa-2,5-diene-4,6-dicarbonitrile
The title 2-aza-bicyclo-[2.2.2]octa-2,5-diene derivative, C(14)H(18)N(4)O, crystallized out with two independent mol-ecules with similar conformations in the asymmetric unit. In each mol-ecule, the three six-membered rings adopt boat conformations. The mol-ecules exist in the enamine form. In the crystal, mol-ecules are linked by N-H⋯O and N-H⋯N hydrogen bonds into a two-dimensional network par...
متن کامل3-Amino-5-(piperidin-1-yl)thiophene-2,4-dicarbonitrile
In the title compound, C(11)H(12)N(4)S, the thio-phene ring is roughly planar, with a maximum deviation of 0.012 (1) Å for the S atom, and makes a dihedral angle of 7.89 (8)° with the mean plane of the piperidine ring, which is in a chair conformation. The crystal packing is stabilized by pairs of centrosymmetric inter-molecular N-H⋯N hydrogen bonds, which results in the formation of a step-wis...

The dihedral angle between the planes of the two aromatic rings of the title compound, C(16)H(13)N(3)S, is 56.7 (3)°. The crystal packing is stabilized by inter-molecular N-H⋯N hydrogen bonds, which link the mol-ecules into chains along [11[Formula: see text]].
متن کامل2-Amino-4-phenyl-5,6-dihydrobenzo[h]quinoline-3-carbonitrile–3-amino-1-phenyl-9,10-dihydrophenanthrene-2,4-dicarbonitrile (5/3)
The asymmetric unit of the 5:3 title co-crystal of 2-amino-4-phenyl-5,6-dihydro-benzo[h]quinoline-3-carbonitrile and 3-amino-1-phenyl-9,10-dihydro-phenanthrene-2,4-dicarbonitrile, 0.625C(20)H(15)N(3).0.375C(22)H(15)N(3), has the atoms of the fused-ring system and those of the amino, cyano and phenyl substitutents overlapped. The fused-ring system is buckled owing to the ethyl-ene linkage in the...
متن کامل4-Amino-5-(2-hydroxybenzylideneamino)benzene-1,2-dicarbonitrile
A new tetra-dentate unsymmetrical Schiff base, C(15)H(10)N(4)O, has been synthesized from 4,5-dicyano-o-phenyl-enediamine and o-vanillin in refluxing ethanol. The dihedral angle between the two benzene rings is 39.0 (1)°. There are intra-molecular O-H⋯N and weak inter-molecular N-H⋯O and N-H⋯N inter-actions.
