rac-Dimethyl [(9-anthr-yl)(4-methyl-anilino)meth-yl]phospho-nate.

Project description:The title compound, C(24)H(24)NO(3)P, crystallizes as a racemate with two mol-ecules in the asymmetric unit. The structural features (bond lengths and angles) of the two mol-ecules are almost identical. The dihedral angle between the anthracene and toluidine rings is similar in the two mol-ecules, with values of 48.36 (9) and 51.15 (9)°. The methyl groups of one of the meth-oxy groups in one mol-ecule is disordered over two sets of sites, the major component having a site occupancy of 0.636 (3). In the crystal, both molecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds.

rac-2-[(2-Chloro-phen-yl)(4-chloro-phen-yl)meth-yl]-1,3-dioxolane.

Project description:The title compound, C(16)H(14)Cl(2)O(2), is a chiral mitotane derivative that contains a dioxolane ring and crystallizes from methanol as a racemic mixture. It was obtained in high yield from mitotane and ethyl-eneglycol in alkaline medium, followed by neutralization with sulfuric acid and extraction with ethyl acetate. The mol-ecular structure is stabilized by an intra-molecular C- H? O hydrogen bond. The dihedral angle between the aromatic rings is 80.1?(2)°. The dioxolane ring adopts a puckered envelope conformation with an O atom as the flap.

1-{6-Chloro-2-[(2-chloro-3-quinol-yl)meth-oxy]-4-phenyl-3-quinol-yl}ethan-1-one.

Project description:In the title compound, C(27)H(18)Cl(2)N(2)O(2), the 2-chloro-quinoline and 6-chloro-quinoline rings are almost planar, with maximum deviations from their mean planes of 0.072?(1) and 0.044?(1)?Å, respectively, for the Cl atoms. The inter-planar angle between these rings is 14.36?(5)°. The inter-planar angle between the 6-chloro-quinoline and phenyl rings is 66.00?(8)°. In the crystal, mol-ecules are inter-linked by weak C-H?O, C-H?? and ?-? stacking [centroid-centroid distances = 3.7453?(10) and 3.7557?(9)?Å] inter-actions.

4-(2-Chloro-anilino)-3-phenyl-furan-2(5H)-one.

Project description:The title compound, C(16)H(12)ClNO(2), featuring a furan-2(5H)-one (?-butyrolactone) core, contains two mol-ecules (A and B) in the asymmetric unit, with different dihedral angles between the central ring and the pendant phenyl and chloro-benzene rings [43.33?(8) and 20.16?(8)°, respectively, for A, and 47.79?(8) and 13.87?(8)°, respectively, for B]. In the crystal, the A mol-ecules are linked into [001] chains by single C-H?O inter-actions. The B mol-ecules also form [001] chains, but their relative orientations in the chains are quite different to those of the A mol-ecules so that adjacent B mol-ecules are linked by two C-H?O hydrogen bonds. Finally, C-H?O inter-actions and aromatic ?-? stacking contacts [centroid-centroid separations = 3.754?(1) and 3.817?(1)?Å] link the chains into a two-dimensional array parallel to (010).

3-Bromo-meth-yl-2-chloro-meth-yl-1-phenyl-sulfon-yl-1H-indole.

Project description:In the title compound, C(16)H(13)BrClNO(2)S, the indole mean plane forms a dihedral angle of 73.59 (19)° with the phenyl ring. The mol-ecular structure is stabilized by weak intra-molecular C-H⋯O inter-actions. The Br atom is disordered over two positions with site occupancy factors of 0.7 and 0.3.

rac-4-Chloro-2-[({2-[(3-chloro-6-hy-droxy-2,4-dimethyl-benz-yl)(meth-yl)amino]-prop-yl}(meth-yl)amino)-meth-yl]-3,5-dimethyl-phenol.

Project description:The title compound, C(23)H(32)Cl(2)N(2)O(2), a potential chiral ligand for coordination chemistry, was prepared by a two-step reaction. The mol-ecule is located on a crystallographic centre of inversion. As a result, the methyl group bonded to the methyl-ene group is disordered over two equally occupied positions, sharing the same site as the H atom of the chiral C atom. As a further consequence of the crystallographic centrosymmetry, the 1,2-diamino-propane unit adopts an anti-periplanar conformation and the two benzene rings are coplanar. The central chain is in an all-trans arrangement. An intra-molecular O-H?N hydrogen bond makes an S(6) ring motif. A C-H?? inter-action links the mol-ecules into one-dimensional chains along the [001] direction.
