11H-Indeno[1,2-b]quinoxalin-11-one
In the title compound, C(15)H(8)N(2)O, the fused ring system is approximately planar, with a maximum deviation of 0.039 (1) Å. In the crystal, weak inter-molecular C-H⋯O inter-actions help to establish the packing.

The title compound, C(17)H(15)NO(2), was prepared from 1-hydroxy-carbazole and 3,3-dimethyl-acrylic acid with a mixture of AlCl(3) and POCl(3) as the cyclization catalyst. Owing to the presence of the -CMe(2)- group, the mol-ecule is not quite planar. In the crystal structre, strong N-H⋯O hydrogen bonds and weaker C-H⋯π inter-actions occur, and a slipped π-π stacking inter-action [centroid-cent...
متن کامل1-Methoxy-11H-benzo[b]fluoren-11-one
In the title compound, C18H12O2, the non-H atoms are nearly coplanar, the maximum atomic deviation being 0.113 (2) Å. π-π stacking is observed in the crystal structure, the shortest centroid-centroid distance being 3.5983 (19) Å. The mol-ecular packing is further stabilized by weak C-H⋯O hydrogen bonds, forming an infinite chain along [100] and generating a C(6) motif.
متن کامل1-Hydroxy-11H-benzo[b]fluoren-11-one
The title compound, C(17)H(10)O(2), is nearly planar, the maximum atomic deviation being 0.053 (2) Å. In the mol-ecule, an intra-molecular O-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, inversion-related mol-ecules are linked by pairs of weak C-H⋯O hydrogen bonds, forming dimers. π-π stacking is observed in the crystal structure, the closest centroid-centroid distance being 3...

In the title compound, C(23)H(23)NO(5)S·0.125H(2)O, the pyrrolidine ring has a twist conformation and the dihydro-pyran ring adopts a half-chair conformation; the two rings are cis-fused. The mol-ecule adopts a folded conformation. The sulfonyl-bound phenyl ring and the pyran ring of the coumarin ring system are stacked over one another, with a centroid-centroid distance of 3.7470 (7) Å; the di...
