Methyl 5,6-dimethoxy-1H-indole-2-carboxylate
The title compound, C12H13NO4, was prepared as a precursor to an indole derivative with possible antimitotic properties. The molecule is very nearly planar; the maximum deviation of any non-H atom from the mean plane of the indole ring is 0.120 (3) Å for each of two methoxy C atoms. The pairs of molecules related by the inversion centre at (0,0,) are connected by two symmetry-equivalent N—H⋯O hydrogen bonds, while the pairs of molecules related by the inversion centre at (0,0,0) exhibit a π-stacking interaction of the indole rings, with an interplanar separation of 3.39 (3) Å
5-Methoxy-1-(3,4,5-trimethoxyphenyl)-1H-indole
The title compound, C18H19NO4, was prepared as an indole derivative with possible antimitotic properties. The planes of the indole and trimethoxyphenyl rings make a dihedral angle of 45.35 (5)° with one another. In the crystal, molecules related by a twofold screw axis exhibit arene C—H⋯arene-π interactions which are 3.035 (1) Å in length
Bis(benzenethiolato)(2,2′-biquinoline)zinc(II)
The title compound, [Zn(C6H5S)2(C18H12N2)], was prepared as a model for future complexes that will be incorporated into light-harvesting arrays. The ZnII atom lies on a twofold rotation axis and the ligands are arranged tetrahedrally around this atom. The benzenethiolate ligand and the biquinoline ligand are nearly perpendicular to one another, making a dihedral angle of 84.09 (5)°. The biquinoline ligand is nearly planar, with a maximum deviation of 0.055 (3) Å from the mean plane of the ring system. In the crystal, the molecules pack in a manner such that the biquinoline ligands are parallel to one another, with a π–π interaction [interplanar distance = 3.38 (1) Å] with the neighboring biquinoline ligand
Bis(2-naphthylmethyl)diphenylsilane
The title compound, C34H28Si, was prepared as an internal standard for diffusion-ordered NMR spectroscopy. The four ligands are arranged tetrahedrally around the Si atom. The two naphthalene systems are nearly perpendicular, making an angle of 86.42 (4)° with one another. A naphthalene system and a phenyl ring are also nearly perpendicular, making an angle of 86.18 (6)° with one another. In the crystal, the molecules pack in columns parallel to the a axis, and exhibit arene C—H⋯π(arene) interactions both within and between columns
