2-Hydroxy-2-(3-oxobutan-2-yl)indan-1,3-dione
In the indane ring system of the title mol-ecule, C(13)H(12)O(4), the hy-droxy-bearing C atom is 0.134 (1) Å out of the plane of the remaining essentially planar atoms (r.m.s. deviation = 0.010 Å). In the crystal, mol-ecules are linked into chains along the b axis by inter-molecular O-H⋯O hydrogen bonds. Additional stabilization is provided by weak inter-molecular C-H⋯O hydrogen bonds.

The title compound, C(22)H(19)NO(2), has potential for use as a new nonlinear optical material. Mol-ecules are almost planar. One C atom of the heterocyclic ring system is disordered over two positions; the site occupancy factors are 0.6 and 0.4.
متن کامل1,5-Bis(pentafluorophenyl)-3-phenylpent-2-ene-1,5-dione
In the title compound, C(23)H(8)F(10)O(2), the three arene rings are twisted one with respect to the other: the two perfluorinated arene rings are tilted to each other by an angle of 60.39 (7)°. They are inclined to the non-fluorinated phenyl unit by 38.85 (7) and 78.74 (7)°. The olefinic double bond adopts an E configuration. The carbonyl groups are not in a coplanar alignment with reference t...
متن کامل6-Methylideneandrost-4-ene-3,17-dione
In the title compound, C(20)H(26)O(2), which is the 6-methyl-ene derivative of androstenedione and a synthetic percursor of exemestane, the steroid A ring approximates to a sofa (or envelope) conformation, with the methyl-ene group adjacent to the link to the B ring lying out of the plane of the other atoms. The B and C rings have slightly flattened chair conformations and the D ring is an enve...
متن کامل11α,15α-Dihydroxyandrost-4-ene-3,17-dione
The title compound, C(19)H(26)O(4), was biotransformed from androstenedione. In the crystal, inter-molecular O-H⋯O hydrogen bonds link molecules into a corrugated sheet, which lies parallel to the ab plane. Ring A has a slightly distorted half-chair conformation, rings B and C adopt chair conformations, while the cyclo-pentane ring D adopts a 14α-envelope conformation.
