6-Bromo-2-(3-phenylallylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one
Mol-ecules of the title compound, C(21)H(16)BrNO, are linked through pairs of N-H⋯O inter-molecular hydrogen bonds into centrosymmetric R(2) (2)(10) dimers. One of the C atoms of the cyclohex-2-enone ring is disordered with refined occupancies of 0.61 (2) and 0.39 (2).
متن کامل6-Bromo-2-[(E)-thiophen-2-ylmethylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one
In the title compound, C(17)H(12)BrNOS, the cyclo-hexene ring deviates only slightly from planarity (r.m.s. deviation for non-H atoms = 0.047 Å). In the crystal, the mol-ecules are linked into centro-symmetric R(2) (2)(10) dimers via pairs of N-H⋯O hydrogen bonds. The thio-phene ring is disordered over two positions rotated by 180° and with a site-occupation factor of 0.843 (4) for the major oc...
متن کامل6-Bromo-1-(1,2-propadienyl)-3-(2-propynyl)-1H-imidazo[4,5-b]pyridin-2(3H)-one
The reaction of propargyl bromide and 6-bromo-1,3-dihydro-imidazo[4,5-b]pyridin-2-one in refluxing dimethyl-formamide yields the title compound, C(12)H(8)BrN(3)O, which features nitro-gen-bound propadienyl and propynyl substituents. The imidazolopyridine fused ring is planar (r.m.s. deviation = 0.012 Å); the propadienyl chain is coplanar with the fused ring as it is conjugated with it, whereas ...
متن کامل3-Bromo-6-nitro-1-(prop-2-ynyl)-1H-indazole
In the title compound, C(10)H(6)BrN(3)O(2), the indazole fused-ring system is nearly planar (r.m.s. deviation = 0.008 Å); its nitro substituent is nearly coplanar with the fused ring [dihedral angle = 4.5 (2)°]. In the crystal, adjacent mol-ecules are linked by weak acetyl-ene-nitro C-H⋯O hydrogen bonds, generating a helical chain running along the b axis.
متن کامل6-Methoxy-2,3,4,9-tetrahydro-1H-carbazol-1-one
The carbazole unit of the title mol-ecule, C(13)H(13)NO(2), is not planar. The dihedral angle between the benzene ring and the pyrrole ring is 1.69 (6)°. The cyclo-hexene ring adopts an envelope conformation. Inter-molecular C-H⋯O and N-H⋯O hydrogen bonds are present in the crystal structure. A C-H⋯π inter-action, involving the benzene ring, is also found in the crystal structure.
