2-Methoxynaphthalene-1,4-dione
The title compound, C(11)H(8)O(3), was isolated from Impatiens balsamina plants (balsam, LIB) grown in our laboratory. The two six-membered rings of the naphthalene-1,4-dione unit are coplanar [maximum deviation = 0.009 (1) Å]. The O and C atoms of the meth-oxy substituent also lie close to the naphthalene plane, with deviations of 0.0090 (2) and 0.047 (2) Å, respectively.

The asymmetric unit of the title compound, C(10)H(8)BrNO(2), contains three crystallographically independent mol-ecules. Two of the N-C-C-Br side chains adopt anti conformations [torsion angles = -179.8 (5) and -179.4 (4)°] and the other is gauche [-66.5 (6)°]. The crystal structure features short Br⋯O [3.162 (5) Å] contacts, C-H⋯O hydrogen bonds and numerous π-π stacking inter-actions [centroi...

In the title compound, C(14)H(8)INO(2), the dihedral angle between the isoindole ring and the phenyl ring of the 1-iodo-benzene group is 84.77 (15)°. There is a short inter-molecular I⋯O contact of 3.068 (3) Å in the crystal.
متن کامل2-[2-(Methylsulfonyl)ethyl]isoindoline-1,3-dione
In the mol-ecule of the title compound, C(11)H(11)NO(4)S, the isoindoline ring system is almost planar with a maximum deviation of 0.008 (3)Å. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ecules into a three-dimensional network. π-π contacts between the isoindoline rings [centroid-centroid distances = 3.592 (1) and 3.727 (1) Å] may further stabilize the structure.
متن کامل2-Acetonyl-2-hydroxyindan-1,3-dione
In the title compound, C(12)H(10)O(4), the five-membered ring adopts an envelope conformation, with the Csp(3) atom at the flap [deviation = 0.145 (2) Å]. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.
