2-(6-Methyl-2,3,4,9-tetrahydro-1H-carbazol-1-ylidene)propanedinitrile
In the title compound, C(16)H(13)N(3), the cyclo-hexene ring adopts a sofa conformation. An intra-molecular N-H⋯N hydrogen bond generates an S(7) ring motif. In the crystal, the mol-ecules are linked by pairs of N-H⋯N inter-actions, forming centrosymmetric dimers with an R(2) (2)(14) motif.

The mol-ecular conformation of the title compound, C(15)H(10)ClN(3), is stabilized by an intra-molecular N-H⋯N hydrogen bond with an S(7) ring motif. The crystal packing is controlled by N-H⋯N and C-H⋯N inter-molecular inter-actions. One of the methyl-ene groups of the cyclo-hexene ring is disordered over two positions with refined occupancies of 0.457 (12) and 0.543 (12).

In the title mol-ecule, C(15)H(11)N(3), the dihedral angle between the benzene ring and the fused pyrrole ring is 1.07 (5)°. The cyclo-hexene ring adopts an envelope conformation: the dicyano-methyl-ene group at position 1 has a coplanar orientation. An intra-molecular N-H⋯N hydrogen bond generates an S(7) ring motif. Inter-molecular N-H⋯N hydrogen bonds form an R(2) (2)(14) ring in the crystal...
متن کامل(E)-2-[(Furan-2-yl)methylidene]-7-methyl-2,3,4,9-tetrahydro-1H-carbazol-1-one
In the title mol-ecule, C(18)H(15)NO(2), the atoms in the carbazole unit deviate from planarity [maximum deviation from mean plane = 0.1317 (12) Å]. The pyrrole ring makes dihedral angles of 1.01 (8) and 18.56 (10)° with the benzene and furan rings, respectively. The cyclo-hexene ring adopts a half-chair conformation. In the crystal, pairs of N-H⋯O hydrogen bonds form an R(2) (2)(10) ring. Mol-...
متن کاملCrystal structure of (E)-2-(furan-2-ylmethylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one
The title compound, C17H13NO2, crystallizes with two conformationally very similar independent mol-ecules (A and B) in the asymmetric unit. In the crystal, the individual mol-ecules are linked by pairs of N-H⋯O hydrogen bonds forming A-A and B-B inversion dimers, with R22(10) rings. They stack alternately up the a-axis direction and are linked by C-H⋯π inter-actions, forming sheets parallel to ...
