Phthalazin-1(2H)-one–picric acid (1/1)
The geometric parameters of the title compound, C(8)H(6)N(2)O·C(6)H(3)N(3)O(7), are in the usual ranges. The three nitro groups are almost coplanar with the aromatic picrate ring [dihedral angles 10.2 (2)°, 7.62 (16) and 8.08 (17)°]. The mol-ecular conformation of the picric acid is stabilized by an intra-molecular O-H⋯O hydrogen bond. The phthalazin-1(2H)-one mol-ecules are connected via N-H⋯O...

In the title compound, C21H14N2O2S, a donor-acceptor type of benzo[b]pheno-thia-zine (bpz) derivative, the thia-zine ring adopts a boat conformation and the bond-angle sum at the N atom is 360.0°. The dihedral angle between the benzene ring and the naphthelene ring system fused to the thia-zine ring is 32.76 (5)°. In the crystal, carb-oxy-lic-acid inversion dimers linked by pairs of O-H⋯O hydro...
متن کامل9,9-Dimethyl-12-phenyl-8,9-dihydro-12H-benzo[a]xanthen-11(10H)-one
The title compound, C(25)H(22)O(2), was synthesized via the three-component coupling of benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. In the crystal structure, centrosymmetrically related mol-ecules are linked into dimers by pairs of inter-molecular C-H⋯O hydrogen bonds. The dimers are further connected into a three-dimensional network by π-π aromatic stacking inter-actions ...
متن کامل12-(4-Chlorophenyl)-9,9-dimethyl-9,10-dihydro-8H-benzo[a]xanthen-11(12H)-one
The title compound, C(25)H(21)ClO(2), was synthesized via the three-component coupling of 4-chloro-benzaldehyde, 2-naphthol and 5,5-dimethyl-cyclo-hexane-1,3-dione. The pyran ring adopts a boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 4-chloro-phenyl ring is almost perpendicular to the pyran ring [dihedral angle = 87.39 (1)°]. In the crystal, mol-ecules ar...
متن کامل9,9-Dimethyl-12-(4-nitrophenyl)-9,10-dihydro-12H-benzo[a]xanthen-11(8H)-one
In the mol-ecular structure of the title compound, C(25)H(21)NO(4), the pyran ring adopts a flattened boat conformation, while the cyclo-hexenone ring is in an envelope conformation. The 4-nitro-phenyl ring is almost perpendicular to the pyran ring [dihedral angle = 89.39 (1)°]. In the crystal, mol-ecules are connected by inter-molecular C-H⋯O hydrogen bonds.
