Crystal structure of bromido(?6-1-isopropyl-4-methylbenzene)(7-oxocyclohepta-1,3,5-trien-1-olato-?2O,O')osmium.

ABSTRACT: In the title compound, [OsBr(C10H14)(C7H5O2)], the central OsII ion is ligated by a hexa-haptic ?6p-cymene ring, a Br- ligand and two O atoms of a chelating tropolonate group. The p-cymene ligand presents more than one conformation, giving rise to a discrete disorder, which was modelled with two different orientations with occupancy values of 0.561?(15) and 0.439?(15). The crystal packing features C-H?O and C-H?Br hydrogen bonding. Aromatic ?-? stacking inter-actions are also observed between adjacent non-benzenoid aromatic tropolone rings.

Crystal structure of 16-ferrocenylmethyl-3?-hydroxy-estra-1,3,5(10)-trien-17-one: a potential chemotherapeutic drug.

Project description:A new ferrocene complex, 16-ferrocenylmethyl-3?-hy-droxy-estra-1,3,5(10)-trien-17-one dimethyl sulfoxide monosolvate, [Fe(C5H5)(C24H27O2)]·C2H6OS, has been synthesized and structurally characterized by single-crystal X-ray diffraction techniques. The mol-ecule crystallizes in the space group P21 with one mol-ecule of dimethyl sulfoxide. A hydrogen bond links the phenol group and the dimethyl sulfoxide O atom, with an O?O distance of 2.655?(5)?Å. The ferrocene group is positioned in the ? face of the estrone moiety, with an O-C-C-C torsion angle of 44.1?(5)°, and the carbonyl bond length of the hormone moiety is 1.216?(5)?Å, typical of a C=O double bond. The average Fe-C bond length of the substituted Cp ring [Fe-C(Cp*)] is similar to that of the unsubstituted one [Fe-C(Cp)], i.e. 2.048?(3) versus 2.040?(12)?Å. The structure of the complex is compared with those of estrone and eth-oxy-methyl-estrone.

Project description:In the title compound, C(18)H(21)IO, the cyclo-hexane ring adopts a chair conformation, whereas the cyclo-pentane ring and the ten-membered tetra-line portions each adopt an envelope conformation. For the five-membered ring, the methine C atom deviates by 0.638?(4)?Å (r.m.s. of the four other atoms is 0.005?Å) and for the ten-membered ring, the methine C atom constituting the flap deviates by 0.671?(3)?Å (r.m.s. of the other nine atoms is 0.066?Å).

Crystal structure of 1,3,5-trimethyl-2,4-di-nitro-benzene.

Project description:In the title compound, C9H10N2O4, the planes of the nitro groups subtend dihedral angles of 55.04 (15) and 63.23 (15)° with that of the aromatic ring. These tilts are in opposite senses and the mol-ecule possesses approximate mirror symmetry about a plane normal to the mol-ecule. In the crystal, mol-ecules form stacks in the [100] direction with adjacent mol-ecules related by translation, although the centroid-centroid separation of 4.136 (5) Å is probably too long to regard as a significant aromatic π-π stacking inter-action. An extremely weak C-H⋯O inter-action is also present.

Project description:In the title compound, [Pb(C(10)H(11)O(2))(2)](n) or [Pb(hino)(2)](n), the lead(II) ion is chelated by two hinokitiolate ligands in a distorted square-pyramidal configuration, with Pb-O bond lengths in the range 2.327 (6)-2.479 (9) Å. The 6s(2) lone electron pair of the lead(II) ion becomes stereochemically active and is directed towards the apex of this pyramid. The crystal structure of the title compound consists of chains formed by the bis-(hinokitiolato)lead(II) mol-ecules situated along the twofold screw axis. The coordination sphere around the lead(II) ion is completed by three additional O atoms, at 2.625 (7), 3.016 (8) and 3.064 (8) Å, from the two neighbouring Pb(hino)(2) units. Both isopropyl groups are rotationally disordered.

17-Deoxoestrone [estra-1,3,5(10)-trien-3-ol]-methanol (3/1).

Project description:Three independent mol-ecules of the title estrone derivative and a mol-ecule of methanol comprise the asymmetric unit of the title compound [systematic name: 13-methyl-6,7,8,9,11,12,13,14,15,16-deca-hydro-cyclo-penta-[a]phenanthren-3-ol-meth-an-ol (3/1)], 3C(18)H(24)O·CH(3)OH. Two of the estrone mol-ecules exhibit 50:50 disorder (one displays whole-mol-ecule disorder and the other partial disorder in the fused five- and six-membered rings) so that five (partial) mol-ecular conformations are discernable. The conformation of the six-membered ring abutting the aromatic ring is close to a half-chair in all five components. The conformation of the six-membered ring fused to the five-membered ring is based on a chair with varying degrees of distortion ranging from minor to significant. Two distinct conformations are found for the five-membered ring: in four mol-ecules, the five-membered ring is twisted about the bond linking it to the six-membered ring, and in the other, the five-membered ring is an envelope with the quaternary C atom being the flap atom. The crystal packing features O-H?O hydrogen bonding whereby the four mol-ecules comprising the asymmetric unit are linked into a supra-molecular chain along the b axis.

Crystal structure of 4-azido-methyl-6-isopropyl-2H-chromen-2-one.

Project description:In the title mol-ecule, C13H13N3O2, the benzo-pyran ring system is essentially planar, with a maximum deviation of 0.017?(1)?Å. In the crystal, weak C-H?O hydrogen bonds link mol-ecules into ladders along [010]. In addition, ?-? inter-actions between inversion-related mol-ecules, with centroid-centroid distances in the range 3.679?(2)-3.876?(2)?Å, complete a two-dimensional network parallel to (001).
