چکیده
In the title compound, C(31)H(27)N(3), the cyclo-hexene ring has an envelope configuration. In the crystal structure, there is an 34 Å(3) void around the inversion center, but the low electron density (0.13 e Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupying this void. No hydrogen bonding is found in the crystal structure.

In the title compound, [HgI2(C22H20N4)2], the Hg(II) cation is situated on a twofold rotation axis and is coordinated by two iodide anions and two imidazolyl N atoms in a distorted tetra-hedral geometry. In the crystal, C-H⋯I inter-actions link the mol-ecules into chains extending in [010], which are further linked into sheets parallel to (100) through C-H⋯N hydrogen bonding inter-actions.

The mol-ecule of the title compound, C(18)H(17)N(3), with the exception of the -C(CH(3))(2) group, is nearly planar [maximum deviation: 0.208 (4), r.m.s. deviation 0.099 (6) Å] and the disubstituted C atom is displaced by 0.679 (2) Å from the mean plane through the remaining non-H atoms. In the crystal, the packing is stabilized by weak C-H⋯π inter-actions.

In the title compound, C25H29FO4, each cyclo-hexenone ring has an envelope conformation with the dimethyl-substituted atom as the flap. The hy-droxy and carbonyl groups form two intra-molecular O-H⋯O hydrogen bonds, as is typical for xanthene derivatives. In the crystal, very weak C-H⋯O hydrogen bonds link mol-ecules into dimers.

In the title compound, C(25)H(32)O(7), the 3-hy-droxy-5,5-dimethyl-cyclo-hex-2-enone rings adopt slightly distorted envelope conformations with the two planes at the base of the envelope forming dihedral angles of 57.6 (4) and 53.9 (9)° with the benzene ring. There is an intra-molecular hy-droxy-ketone O-H⋯O inter-action between the two substituted cyclo-hexane rings as well as a short intra-mo...
