12-(4-Meth-oxy-benzo-yl)-2-methyl-benzo[f]pyrido[1,2-a]indole-6,11-dione.

ABSTRACT: In the title compound, C(25)H(17)NO(4), the indolizine fused naphthaquinone unit is approximately planar [r.m.s deviation = 0.0678?Å] and makes a dihedral angle of 57.82?(5)° with the benzene ring of the meth-oxy-benzene group. The naphtho-quinone O atoms deviate, in the same sense, from the mean plane of the fused six-membered rings by 0.2001?(14) and 0.0516?(14)?Å. In the crystal there is ?-? stacking of inversion-related pairs of mol-ecules [inter-planar spacing = 3.514?(2)?Å].

In the title compound, C(25)H(17)NO(4), the indolizine fused naphthaquinone unit is approximately planar [r.m.s deviation = 0.0678 Å] and makes a dihedral angle of 57.82 (5)° with the benzene ring of the meth-oxy-benzene group. The naphtho-quinone O atoms deviate, in the same sense, from the mean plane of the fused six-membered rings by 0.2001 (14) and 0.0516 (14) Å. In the crystal there is π-π stacking of inversion-related pairs of mol-ecules [inter-planar spacing = 3.514 (2) Å]. ...[more]

12-Benzoyl-2-methyl-naphtho-[2,3-b]indolizine-6,11-dione.

Project description:In the title compound, C(24)H(15)NO(3), the fused naphthaquin-one-pyrrole unit is approximately planar, the naphthaquinone ring system making a dihedral angle of 2.91?(10)° with the pyrrole ring. The plane of the pyrrole ring makes a dihedral angle 61.64?(14)° with that of the benzene ring of the benzoyl-methyl-ene group. The crystal structure is stablized by intra-molecular C-H?O inter-actions.

3-Acetyl-5-hy-droxy-2-methyl-anthra[1,2-b]furan-6,11-dione.

Project description:The asymmetric unit of the title compound, C(19)H(12)O(5), contains two independent mol-ecules, both slightly buckled along an axis passing through the C=O bonds of the anthraquinone ring system (r.m.s. deviation of non-H atoms = 0.082 and 0.148 Å): the benzene rings are twisted to each other by 4.3 (3)°in one mol-ecule and 10.6(3)° in the other. In both mol-ecules, the hy-droxy group forms an intra-molecular O-H⋯O hydrogen bond. The two independent mol-ecules inter-act by π-π stacking with a centroid-centroid distance of 3.539 (2) Å between hy-droxy-benzene rings of adjacent mol-ecules.

Project description:In the title compound, C(22)H(14)N(2)O(2), the five rings of the mol-ecule are not coplanar. There is a significant twist between the four fused rings, which have a slightly arched conformation, and the pendant aromatic ring, as seen in the dihedral angle of 13.16 (8)° between the anthraquinonic ring system and the pendant aromatic ring plane.

N-(4-Meth-oxy-benzo-yl)-2-methyl-benzene-sulfonamide.

Project description:In the title compound, C15H15NO4S, the dihedral angle between the aromatic rings is 80.81 (1)° and the dihedral angle between the planes defined by the S-N-C=O fragment and the sulfonyl benzene ring is 86.34 (1)°. In the extended structure, dimers related by a crystallographic twofold axis are connected by pairs of both N-H⋯O hydrogen bonds and C-H⋯O inter-actions, which generate R 2 (2)(8) and R 2 (2)(14) loops, respectively. A weak aromatic π-π stacking inter-action is also observed [centroid-centroid separation = 3.7305 (3) Å].

N-(3-Meth-oxy-benzo-yl)-2-methyl-benzene-sulfonamide.

Project description:In the title compound, C15H15NO4S, the dihedral angle between the methyl- and meth-oxy-substituted benzene rings is 88.99 (12)°. An intra-molecular C-H⋯O hydrogen bond occurs. In the crystal, adjacent mol-ecules form inversion-related dimers through strong N-H⋯O hydrogen bonds, generating R 2 (2)(8) loops. The dimers are further connected through C-H⋯O inter-actions that form C(8) chains parallel to (001).

Two aromatic π-π stacking inter-actions [centroid-centroid separations = 3.6150 (1) and 3.6837 (1) Å] generate a three-dimensional architecture.
